How to archive hifi sound on Pc


Any of the readers of this article can always download several MP3 songs and listen to them by simply connecting a pair of multimedia speakers to the computer. There is nothing wrong with this, but you should always be aware that you can get higher quality sound on a computer. We have spent a considerable amount of time researching this issue, and the result is high-quality music reproduction on a computer that is as good as sound from a CD player.

What are the benefits of using a computer to play music?


- On a computer, you can create a well-structured collection of music.
- Thanks to tags, you can search and sort music by artist, album title, genre, etc.
- Create playlists to listen to your favorite songs.
- Synchronize with portable players
- Simultaneously use in multiple rooms thanks to DLNA technology


DLNA (Digital Living Network Alliance) is a standard for data exchange between any AV devices connected to a home computer network. It allows the operation of one device with the help of another, to transmit video or audio streams over the network. It is possible that DLNA will become the same standard for AV devices that TCP/IP has become for the World Wide Web.
In order to receive the "DLNA" logo, a product must pass the necessary certification, which ensures that devices from different manufacturers can work together.
DLNA terminology
1. DMS -- Digital Media Server - a digital media server, a device that contains music and video
2. DMP -- Digital Media Player - a digital media player - a device that plays music or video
3. DMR - Digital Media Renderer - a digital media renderer - a device that plays music or video that can be controlled by a remote controller.
4. DMC -- Digital Media Controller - digital media controller - software control of the renderer, works like a remote control

Recordings on Audio CDs are 16 bits wide and sampled at 44.1 kHz, which complies with the Redbook audio standard. Modern sound recording is performed with a bit depth of 24 bits and a sampling frequency from 44.1 to 192 kHz. But, even a 24-bit/96 kHz recording cannot be played with a CD player, since this bit rate is not supported by the Redbook standard. Before recording high resolution soundtracks on CD, downsampling with dithering up to 16 bits/44.1 kHz should be done.
You can play Hi-Res audio on PC if your audio system (DAC) supports it. If not, the audio files can usually be played back automatically downsampled to a bitrate supported by your audio system.
If you are planning to buy new Hi-Res audio equipment, then keep in mind that it must support at least 24/96 format.
The catalog of high-resolution phonograms available for download via the Internet is not yet very large, but it is constantly growing.


Downloading files from the Internet
CDs are slowly disappearing. People buy CDs less and less, they download music files. Most websites offer MP3s. Gradually, the bitrate of music files is growing, as the speeds on the Internet are growing and the cost of network storage is falling (in terms of one storage unit). Lossless music formats are still not ubiquitous, but their availability is growing every day.

For real collectors who have a large collection of music, this collection is of great value, both tangible and intangible. Sadly, in the event of a fire, you can lose all your music discs. However, in the case of music files, you can play it safe and store a copy on another server away from home.

Sound quality
This aspect is very important for music lovers.
For example, the laptop itself is not designed for high quality sound reproduction. You can see for yourself, just take the headphones and connect them to the appropriate output of the laptop. In very rare cases, the sound quality can reach the average level.
When organizing a modern computer-based audio system, you can use a decent sound card or USB-to-SPDIF converter and connect your trusted DAC digitally, or connect the USB DAC directly to your laptop. The sound quality can reach a very high level. Your computer will be able to play as well as a CD player.


In general, when creating a modern audio system based on computer technology, you can choose one of three options. This is a PC audio, music server or network audio player.

Music server .

If you like the convenience of using computer technology when listening to music, but you do not want to install a computer in the listening room, then you should pay attention to the music server .

Such devices look exactly like audio equipment, some manufacturers in their advertising texts also emphasize that these devices are not computers.

Indeed, a good marketer should not lie. On a music server , you won't be able to send e-mail, open a browser, or do anything other than listen to music.

If you open the lid of these devices, then inside you will invariably find a computer stuffing with a sound card and an operating system. Without these components, we cannot work with digital sound.

You need to understand that a music server is a tool for storing and managing your music collection. It makes working with your collection much easier, which is almost as important as the sound quality of the system.

What you should pay attention to when choosing a music server 

- Backup (backup). Check if it is possible to backup and transfer your music collection to another server.
- Access via network. Check if you can access audio files over the network. For example, in order to transfer music files to NAS (Network Attached Storage). In some models, network access to the music folder is blocked.
- Working with tags. Tags allow you to quickly sort music by artist name, genre, etc. What to look for: is it possible to manually enter and edit tags. In some cases, you may come across files without tags or with tag errors. It is also worth paying attention to the support for cover art (album cover image). For classical music, the presence of the "Composer" tag is also important.
- Work stability. Before buying, you should read user reviews in the forums. Since the device usually uses proprietary software, it can contain many bugs, which leads to instability in operation.
- Performance. Any device will work fine if only a couple of CDs are loaded into it. And what can happen if a collection of 20,000 tracks or more is uploaded to the server. Some devices from a heavy load may “freeze” or start to “slow down”.
- Iron. Check out what's inside. This may not be easy to do, but if you have a normal computer inside, you can compare the price with a good low-noise PC equipped with a high-quality sound card or an external DAC.
- Noise level. The device will be in the listening room. Fans and hard drives make quite a lot of noise. The design without fans and good sound insulation of hard drives are welcome.
- Digital output. If you are not satisfied with the sound quality of the analog outputs, you can connect an external DAC of your choice to the digital output.

Audio transmission over the network (streaming)

As an alternative to a PC, network players can be considered.
In fact, a network player is a simplified computer connected to a home network. One of the essential advantages of the network player is the lack of moving parts, fan and hard drive, which guarantees silent operation.
Most detailed devices have both analog (RCA) and digital outputs. Thanks to this, connecting to the audio system is not difficult.
Most network players support UPnP/DLNA standards.
Take a look around, you may already have a couple of devices at home that support network streaming. For example, Vista/Win7 operating systems support the UPnP standard. NAS often have a built-in UPnP server. New TVs are often network capable and support the UPnP standard. If desired, you can set up network streaming between these devices.


You can directly play music on your PC. You can use your computer to play music over the network. Also, a PC is often used to store and catalog your music collection.
For a quick start, you can use the computer that you already have. While you can not worry much about the sound quality. First, you should learn about many things that affect the quality of music playback on a PC.

Where to start

In audiophile forums, it is suggested to start by creating a computer copy (rip) of an audio CD using an optical drive. For this, it is recommended to use the EAC program. To listen to music on a PC, it is recommended to use the Foobar player. The basic setup of the Foobar software player is not difficult. However, achieving high-quality Hi-Fi sound on a computer is not always easy. If you are not deeply computer savvy, then you'd better take a different path into digital music.

Operating Systems

It should be noted that the three main operating systems used in personal computers are Windows, Apple OS X and Linux. You shouldn't be learning about computer audio and switching to a new operating system at the same time. Use the OS you are already used to.
On the forum pages, you can find numerous fights between Mac and Windows fans (people who use Linux are usually busy working to join them). But so far no serious arguments have been found for choosing one or another OS, in terms of sound they are approximately the same. When properly configured, each of them is capable of providing sound output in bit perfect mode. The "hardware" required for the operation of these operating systems is also no different. Of these three systems, Windows is the most omnivorous in terms of hardware.

Music collection

It is worth starting work with music with a small collection (30-40 CDs). If you have downloaded MP3 or FLAC files, you can add them as well.

If you immediately use your real collection of considerable size, then everything will slow down, which will interfere with experiments comparing the quality of work of different players or when adding tags. Also, if you accidentally do something by mistake, it will be easy to fix for a small number of files.
Working with the collection will help you formulate software requirements.
Rip multiple lossless audio CDs.
Check that the disk information that is automatically populated from the Internet is correct. Listen as the media player plays these rips.
Try to rip a music album that consists of several CDs.
If you have a lot of classical music in your collection, you can also check if there is a tag for adding a composer and how easy it is to split CDs into individual pieces.


If you plan to use a computer as a source, you will need a software media player. If you will only use it to store your collection, then you will need software to create rips and tag audio files.
The two main players Windows Media Player and iTunes have a clear interface and cover all basic needs.
Most software media players do a good job of ripping audio CDs. But there are also specialized programs for creating disk images, such as dBpoweramp and EAC. For example, we really like dBpoweramp. It's fast, supports AccurateRip, offers accurate metadata for tags, and has a quality format converter.
Do software audio players differ in sound?
We will consider this issue in more detail in a separate article. In our experience, the effect on the sound of the player is much less than that of the driver that works in conjunction with it. In JRiver and Foobar players you can choose different drivers to work with. This allows you to fine-tune your system and find the sound that you like best.

Our recommendations

We advise you to choose a player that meets the following criteria:
- Support for major lossless formats, including FLAC
- Ability to select an audio driver, such as ASIO or WASAPI
- Saving and adding tags to audio files
Unfortunately, iTunes and WMP do not fully meet these requirements . We suggest you take a look at JRiver Media Center (our choice), Foobar or a more elegant version of freeware - MusicBee. If you are a classical music lover, then take a look at MusiCHI.


The easiest way to connect a computer with a sound card is to connect using a mini jack cable - 2xRCA. It's an easy and cheap way to get started, but don't expect serious sound quality from it.
To connect a desktop computer with a discrete audio card installed, use the audio line-out.
DACs and amplifiers/receivers can be connected via the SPDIF digital interface, via an electrical coaxial or optical channel, but, unfortunately, many computers do not have an SPDIF output. In this case, you can use a USB to SPDIF converter.
Now on sale you can find a large number of USB-DACs. New models support bitrates up to 24/192, and also use asynchronous connection. DACs have a USB input and an analog output, so they act as a bridge between the computer and the analog amplifier. Some models have volume control and a headphone output.
Choosing the Right Configuration
Quite decent sound can be obtained immediately after unpacking the device from the box. However, it is recommended that you make a few additional settings in the sound control panel on your computer.
In digital processing, almost any DSP signal processor makes changes with the digital stream. In the audiophile purist circle, any change to the digital audio stream is considered to be detrimental to the sound and "bit perfect" is their Holy Grail.
However, DSP can be useful when working in active crossover mode or when adjusting the sound to room acoustics.
All operating systems are capable of converting the sample rate in the audio stream. In most cases, such a conversion does not improve the sound quality, since writing such a conversion software is not an easy task. K-mixer from Windows XP is one such infamous example. In subsequent articles, we will give recommendations for the correct settings for all operating systems and USB DACs.

RIPing discs

According to our observation, creating copies of discs occurs in two stages:
1. Creating images of audio discs for the entire collection
2. Re-ripping discs using the correct technique Ripping an
audio disc is a little different from simple copying.
The contents of the disc are not just copied, but also converted into an audio format that is used in computers.
Often, when creating a rip, tags are immediately filled in using online databases.

Audio Format

When you rip your discs, you must decide which audio format to choose.

Since the volume of modern data storages is calculated in terabytes, you should not save disk space and you can safely choose a lossless format. The choice of implementing a lossless format is not very important, since you can find many programs for converting from one format to another. Proprietary audio formats can be found on specific operating systems. But since your computer is most likely running Windows, your NAS server is running Linux, and your smartphone is running Android, it's best to choose one of the common formats that can be used on all operating systems.
Audio players use tags to display information such as artist, album name, etc., so you need a format with good tag support. In this case, for example, the WAV format will not work.
It is also desirable that the audio file format also supports the ability to add tags. Otherwise, there is a danger of losing a significant part of meta-information when migrating from one system to another.
Media players usually store information with metadata of music files in a separate library (database) and write it to audio files in the form of tags, if the format allows it. If the audio file does not support recording tags, then working in one media player, you will encounter no problems. But, when you transfer audio files to another player or other device, you may find that some of the information has disappeared. Most often this happens with the WAV format and with added tags that have a proprietary format.

Filling in tags

When creating a rip of an optical audio disc, the tags are often filled with meta-information received from the Internet. We will talk about this in more detail later.
The most popular sources of meta information are FreeDB and Amazon. If you are a fan of classical music, then it is better to use the AMG base.
Rip programs like dBpoweramp can extract metadata from AMG, SonataDB, Music Brains and FreeDB. You can examine the quality of each source and choose the one that suits you best before you start copying your CDs to your computer.

Creating accurate rips with AccurateRip

The idea that errors can occur when ripping an audio CD can be a big concern for audiophiles. Many ripping programs provide the AccurateRip function, which provides a comparison of the files received after the rip with a database of files received by other users. The coincidence of files usually indicates that the rip was carried out without errors.
To create disc rips, you can choose well-known programs such as EAC or dBpoweramp, which provide AccurateRip support. But WMP or iTunes players can also rip.

Audio formats

On the net you can find a lot of controversy around the formats and their differences in sound quality.
Here are typical topics of such disputes:
- The WAV format is superior in sound quality to any lossless formats with compression
- Apple's lossless format has sound defects
- MP3 files with a high bitrate are indistinguishable from a CD
- AAC format sounds much better than MP3
- True high-res must be in 24/176 format
You can participate in the comparison of formats yourself. To do this, rip several tracks and blindly test them. Modern lossy codecs (codecs with lossy quality) are good enough that you can also include them in testing.
Once again, let's recall the WAV format: despite what it considers the most “honest”, sooner or later you may encounter an unpleasant surprise when working with it.
Our recommendations for choosing an audio format:
- Lossless
- Supported by your media player
- Supports the tagging system


Having created a music collection on a computer, you most likely want to use it on portable equipment. Often people create two music libraries, one in lossless format and the other in MP3.
One of the interesting solutions for portable support is a media player with a transcoding function. Regardless of the format in which the music is stored, when a portable player is connected, all music is converted on the fly into a format understandable to him. Transcoding frees you from creating a second library of audio files.


Once you've become familiar with the basic principles of computer audio, you can start experimenting. You can use various media players, change drivers, select bit perfect mode, etc. You can also download a huge amount of music from the Internet. This is one of the significant advantages of computer sound.

Based on materials from The Well-Tempered Computer


 Why do speakers sound bad? Or rather, why don't you like the sound? Here many factors take place and, moreover, of a different nature. The following can be definitely noted (moreover, the so-called canons when buying speakers and amplifiers, namely a certain price ratio, sometimes do not work) - everything is important in the path. Starting from the quality of the material being played, to the acoustic properties of the room itself. The connection is important - the speakers and the amplifier, the source is very important, how it will feed the material to the input of the amplifier. In any case, it is necessary, of course, if there is such an opportunity, to listen to several systems before purchasing. And as a result - like it or not.


 There should be no other assessment. Objectively, in my opinion, the gain knob should not rise above 11 o'clock, the speakers should play legibly at low volume. One more point. It's like modern football. Previously, there were no such powerful commercial and marketing components. They played more from the heart, and the technique was produced in the same way, from the heart. There was no such abundance, of course. The prices were more elevated. And what to do in our modern conditions? Determine a budget and listen! It's nothing you can do. You can also go along the path of acquiring a vintage, and why not? But here it is necessary to understand well, to acquire from people or organizations with an unsullied reputation, otherwise there is a great risk of running into something completely different from what you expected.

 And then you want to listen to music! It's nothing you can do. You can also go along the path of acquiring a vintage, and why not? But here it is necessary to understand well, to acquire from people or organizations with an unsullied reputation, otherwise there is a great risk of running into something completely different from what you expected. And then you want to listen to music! It's nothing you can do. You can also go along the path of acquiring a vintage, and why not? But here it is necessary to understand well, to acquire from people or organizations with an unsullied reputation, otherwise there is a great risk of running into something completely different from what you expected. And then you want to listen to music!


Several times people have contacted with "non-sounding" systems. In one case, the source was changed - the problem was solved. In another case, they did without replacing the source - the interblock saved the situation. The $500 cable prevented the replacement of the source (the purchase of which would have cost $1500 in today's money). In the first case, there were speakers PMC OB1, amplifier - Electrocompaniet ECI-5 MK II. Source - Marantz ND8006. The source was changed to Carry Audio CD-500. In the second case, there was a CD-player and amplifier Exposure 2010S2, speakers System Audio Mantra 30. We decided to change the interblock and took NordOst Red Dawn LS 0.6m. Everything fell into place.


More interesting was the case with the speakers. There was an Accustic Arts Power ES amplifier, a wonderful CD-player of the same brand, I don't remember exactly the model, and the speakers - Sonus Faber Venere 3S. The man was not at all happy with the sound. He listened mainly to Hard-n-Heavy, metal (Manovar, Maiden, UDO), Rammstein, Dark Funeral, Death and many other things like that. Changed the acoustics to PMC Twenty 24 and voila!


The opposite was the case. The customer already had a Venus 3c from Sonus Faber, a Burmester 101 amplifier ... I didn't like it! Solved the problem - Arcam FMJ A49. The person is satisfied, because he did not want to change Venus, and it is understandable - white varnish, good-looking. And immediately the returned Burmister came to the rescue literally in the same week. The client really liked the B&W CM10. Yes, they are beautiful. But they are very demanding on the amplifier. Burmester 101 played great!

If you analyze it according to the so-called canons ... alas, sometimes it even seems strange to make such a choice, but with all the variety, exactly as I wrote above, and it turned out! People are still grateful, because they are no longer looking for anything and do not want to modify their systems. Of course, such parameters as input / output impedance, sensitivity of acoustic systems and current characteristics of amplifiers are also objectively important. But the ligaments were different, in my opinion, very strange)). How do you like the Elac 240 and Rotel AV receiver? And people really liked.



Many music lovers are faced with a choice - which speaker system to take: active or passive?

 In short, I want to talk about the differences between them and some of the features. 

Active speaker system Are speakers with built-in amplifier (s) in the cabinet. The manufacturer already at the design stage matches the pair: speaker - amplifier as much as possible in all input / output characteristics. Immediately about the pros. Due to the optimal matching of the speakers with the amplifiers, it is difficult to disable the acoustics itself, or rather the chances are less (here and there, as a rule, or the nonlinear distortions are minimized, and physically - excessive input power is very difficult to “kill” the speaker systems, it is necessary as they say, try). 

There are no passive filters (crossovers) in cases of biamping / triumping circuits, as a result - there is practically no signal loss and distortion is practically minimized. No speaker cable used !! Which can bring something of its own to the sound, and when using long enough lengths, there will be losses. Cons, but I would say features .. In general, the system is less reliable and, if the amplifier fails, rather unpleasant problems already arise. At least one 220V outlet is required. If you decide to go along the path of passive speakers + amplifier / receiver, then crossovers, speaker cables appear, but! It is possible to experiment with sound when choosing a pair of speaker systems - amplifier. Those. loudspeakers can be given either a monitor character of sound, or an emotional one. And, some music lovers and audiophiles begin the selection of their system with the purchase of an amplifier. Why not?! These are, perhaps, the main differences. I would like to add that, as a rule, all modern active hi-fi / hi end speakers have wireless technologies, all modern interfaces for connecting signal sources (this is usually 3-4 HDMI, at least one optical and coaxial connectors, analog RCA input).

In terms of functionality and capabilities, this is the presence of a DAC and a phono stage (such as MM). But if you consider the line of the manufacturer Canton - Vento Smart, then you can build a home theater without wires at all! Moreover, at least 5.1 (out of full-fledged). Pay attention to active wireless speakers from manufacturers such as Klipsch (Sixes), Totem (kin play bluetooth), KEF (LSX, LS50 wireless). They sound full-bodied, for small rooms it will be great! Sometimes you think, where does that come from?)). But if you consider the line of the manufacturer Canton - Vento Smart, then you can build a home theater without wires at all!

Sometimes you think, where does that come from?))


Disadvantages and Advantages of Passive Speakers

Let's start with the cons of a passive speaker system:

  • In passive systems, either an average amplifier is used. There is no need to expect high-power sound from it and it will always play in average quality, since it is designed for different speakers.
  • A good amplifier can also be built into passive systems, but in this case it will only interact with certain speaker models specially provided by the manufacturer.
  • Note. The limitation of passive speakers to a good class amplifier is understandable. The fact is that the manufacturer cannot know in advance under what acoustics their amplifier will function and produces it of average quality so that it fits everywhere.

The next disadvantage of a passive speaker system lies in the heating of all electronics, including the built-in crossover. It is on this detail that the main output power in passive speakers is focused and the crossover does not withstand.

Acoustic crossover

Note. An acoustic crossover is a device that separates signals by frequency. If the crossover is high-frequency, then it is able to pass high frequencies without changes, but low frequencies pass through them with some attenuation.

In contrast, low-frequency crossovers pass low frequencies but suppress high frequencies. If the crossover in the speaker system overheats, the filtering of frequencies does not occur and the music starts to sound chaotic.

Another disadvantage of a passive speaker system is the performance of the amplifier's power. The point is that loudspeakers must be able to cope with the incoming power at critical moments.

In other words, the power of the amplifier must always be less than the power of the speakers, otherwise the latter will break. The disadvantage in this case is the fact that in passive systems there is no feedback from the amplifier, which can no longer track the load and supply less power at the time of heating or other critical situations.

Passive speakers are heavier than speakers.

To tune passive acoustics, you need to have highly specialized knowledge.

In passive systems, there are more different components.

Pros of passive Speakers:

Only one speaker cable is needed to connect .

You can choose the amplifier yourself.

There is a possibility of more precise system tuning.


Advantages and disadvantages of an active speaker system

Let us now consider the advantages of active acoustics over passive ones:

These systems always provide feedback between the amplifier and the speakers. This makes it possible to automatically monitor the load, reducing it if necessary.

Thus, early failure is prevented and a long service life of active speakers is ensured.

Note. Even a small active subwoofer will have a reliable output, because the amplifier is directly connected here to the speakers, thereby achieving maximum efficiency.

The crossover in active acoustics systems does not heat up at all and the speakers are able to filter the audio signal for a long time. There are no problems with the power ratio between the amplifier and the speakers.

The amplifier is pre-configured for the speakers, as the manufacturer knows the characteristics of his system.

Active acoustics have a high sound quality compared to passive speakers.

In active acoustics, the sound quality is not affected by the distance, so the speakers can be placed as you like - in the trunk, under the ceiling, and so on.

Compared to passive speakers, active speakers have a longer service life.


Disadvantages of an active speaker system:

First of all, it is, of course, the price, which is much higher. Compared to passive speakers, active subwoofers are always more expensive.

Using additional commutation - signal and network cable to each speaker.

Problem with replacing the amplifier if it fails. With passive systems, everything is simple. The amplifier deteriorated, bought a new one and replaced it.

In active systems, the amplifier is built-in and therefore repairs are more difficult.

According to some experts, active acoustics are afraid of moisture much more than passive ones. In this regard, the failure can be quick.

On the other hand, as it was written above, active acoustics are “long-lived” by default.

Amplifier modules in active systems for the most part, especially in Chinese models, are of budget class, which can in no way be regarded as an advantage.

The advantages and disadvantages of each of the systems were listed above.

Now let's compare these systems again in order to be able to make the right choice:

From a design point of view, active acoustics looks more attractive than a competitor in the face of passive speakers, due to the implementation of sound amplification. As mentioned above, active acoustics implies a built-in amplifier that performs automatic tuning, and passive acoustics receives an amplified signal from the outside.

Because of this factor, passive speakers are priced cheaper than active ones, and the price in our country in most cases will determine the choice.

Active acoustics always sound the same. It is because of this that it is generally accepted that they are better than passive subwoofers, where the frequency filter often heats up and the amplifier is not able to reduce the power in a timely manner.

But if you can choose a good and expensive amplifier for passive speakers, then the sound will be the same as that of active speakers, if not better.

Modernization of the system is easier to carry out on passive acoustics. At any time, passive speakers can be connected to a more powerful amplifier with better performance, thus achieving high-quality sound.

But the acoustic systems will not allow this, since they are completely dependent.

Note. Passive columns are considered by experts as a more flexible option. So, with the release of more advanced sound amplifiers, passive subwoofers are taking on new life.

Acoustic active loudspeakers have been the lot of professionals for many years. It is because of this that manufacturers often do not try to give them a more attractive appearance.

And because of this, the aesthetic component suffers. Passive subwoofers, on the other hand, if you look at them, are always beautifully made, since the manufacturer is interested in their relevance.

So, everyone can make a choice based on the above information. If you need professional acoustics, where each sound timbre will be considered as something whole, there is nothing better to find active acoustic systems.

If acoustic speakers are installed in a car by an amateur for the sake of listening to good music, then passive speakers are considered as a more flexible option, especially since they are cheaper and their appearance is always at the highest level.

Instructions on how to install acoustic systems in a car with your own hands are downloaded from the Internet or come complete with speakers. During the installation process, it is recommended to watch a video or photo - reviews of the installation of the system by professionals.

The price of professional speaker installation is usually not high, but it is still advisable to do it yourself.





I want to share with you my feelings after listening to records on various devices. So let's get started. 

Records: 1. Album LULU (Lou Reed & Metallica), recorded in San Rafael, California; 

2. Album For All Tid (debut album of my favorite band Dimmu Borgir), Nuclear Blast, Germany; 3, 4. Albums Sunset Mission and Black Earth (Bohren & Der Club of Gore), [PIAS]; 5. Album Innamoramento (Mylene Farmer), Polydor. There is no desire to write about the nuances, there are intentions to share in general the emotions from listening to the aforementioned plots on different techniques.

1. LULU, Bohren. Equipment: acoustics Klipsch Heresy III, amplifier Leben CS 300, turntable - VPI Classic 2 (Ortofon 2M Black), phono stage - VPI Cliffwood. This set was collected by his old friend from Kolomna about five years ago .. There are a lot of impressions, I listened to the albums twice, one after the other. Premises - 25 squares, ceilings 3.20. Just furniture, bookshelves, carpet, no sound processing. We started listening to vinyl after getting acquainted with the Cary CD 500 CD-player. Tatiana got to know more precisely, I know and love this unit for a long time, but she just got it from a friend. The collection is large, but we listened to AC / DC The Razor's Edge, Accept Balls to the Wall. Great! The control of acoustics is complete, the presentation is clear, the sound is detailed, interesting, a bunch of what you need! The records were played differently, but also amazing! Rainy autumn mood from the Bohrens, dive into the studio with Hetfield and Lou Reed. And in conclusion, I say, come on Mylene Farmer (Tanya is a seasoned rocker, but Farmer, like me, loves it very much, especially this album). The vocals are wonderful, the atmosphere during playback threw me back 8 years .. The stage of the speakers is excellent, the detail is high, the picture is solid, everything is in order with the bass, or rather, I liked it.

2. Dimmu .. I heard it on Stax! Headphones SR-009, amplifier - SRM T-8000. Player - Music Hall MMF 5.3se (Ortofon 2M Bronze). What I heard in these headphones, I have never heard it before. It just didn't happen! New sounds, new details. Here he is, the nascent Norwegian Black! And this feeling is only on SR-009, no less !!! The rest before them is a compromise. So if you do not want bulky and not very acoustics, amplifiers (43cm wide and more), a bunch of cables, then this kit is for you! To clarify, these are open-type electrostats. Those. everything that you listen to will be heard by others.




Comparing conventional acoustics (computer, from musical centers, from a set of boxed home theaters from Eldorado, MVideo, Mediamarkt, etc.) with Hi-Fi / Hi-End, first of all, it is necessary to clarify the terms themselves. Hi-Fi - high accuracy (reliability) literally translated. In the presence of impeccable, or close to it, musical material, when listening to it through high-quality acoustics, the listener will receive real pleasure, thanks to the detail, width and depth of the stage, the correct tonal balance, articulated bass. This is the result of the painstaking work of development engineers who accurately calculate the speaker enclosures, use advanced technologies, high-quality element base that is used in filters, high-quality speakers. For the most part, ordinary acoustics are faceless, at best they play at high volume without audible distortion, but at low volume everything disappears somewhere ... Acoustic systems of hi-fi manufacturers have their own recognizable handwriting, manner of reproduction, because materials are used different, with parasitic everyone struggles with resonances in their own way (you can pay attention to the speaker cases, they are often found with non-parallel edges, sometimes very heavy specimens come across). Hi-End acoustics are uncompromising. As a rule, the developer provides carte blanche to the engineering group, and they, without looking at the financial component, begin to develop the product using expensive processes and technologies, selected element base and very expensive cases. This is for sophisticated music lovers who can afford such speakers. It is important to note here that a music lover listens to music, and an audiophile, rather a technique, using musical material.

But, like music lovers, and audiophiles are found in both categories. Sometimes the categories of technology and the categories of listeners are blurred. The high-end can be quite affordable for the money, and the hi-fi can be exorbitant. The music lover calms down with a further search for equipment, having purchased a set, an audiophile in rare cases stops at this. What is hi-fi,



What amplifier to choose for acoustics? This is one of the most important issues when building a sound reproduction system. Here we will talk about stereos.


One category of people first of all acquires acoustics, then an amplifier for it, while others start with an amplifier. But in the end, after all, the acoustic system, together with the room where it is installed, produces sound, and the role of the amplifier is to fully reveal the acoustics to which it will be connected. The amplifier can give a monitor or emotional character to the sound of a particular speaker system. Someone buys a tube amplifier, someone is a transistor, and still others are a hybrid (the input amplifier stage is built on tubes, the final one is on transistors). Here lamps and transistors are amplifying elements of equipment. You can also purchase a complete amplifier at once, which is also called integral, where the preliminary amplification path is in one case with the final one, or separately - the preamplifier in one case, the final one - in the other. The character and quality of sound is primarily influenced by the preamplifier / amplification stage, while the final one serves as a kind of buffer between the preamplifier and the acoustics, which often also greatly affects the sound quality in the end. The amplifier must have a power reserve in order to comfortably listen at low volumes, as well as at high volumes without distortion. As they say, there is never a lot of power, and I totally agree with that. If we talk about a transistor amplifier (the circuit can be on bipolar or field-effect transistors), it has a higher efficiency than amplifiers whose amplification circuit is built on lamps, high reliability and ease of use. But there are also features (or disadvantages). In a transistor amplifier, one cannot do without the use of such a circuit solution as OOS (negative feedback), which can be both local and general. This is done to minimize harmonic distortion, and to obtain an acceptable output impedance for matching the amplifier to the speaker system. By using high-quality transistors, you can avoid the use of a common OS and use only local OSs, since common feedback introduces into the signal larger values ​​than local intermodulation distortions,

A good tube amplifier is very expensive, has a lower efficiency, but they have no OOS, it is easier to match it with acoustics in terms of its internal resistance, and it has a simple circuitry. A good tube amplifier weighs a lot, thanks to the use of an output transformer to match the acoustics, which ultimately affects the sound. But the consequences from using a transformer are much less than from using negative feedbacks. As a summary, we can say the following - listen, compare various amplifiers, acoustic systems, using as much material as possible and stop at what you really like and, so to speak, lay on your heart. Among the manufacturers of transistor amplifiers, I want to note: Bryston, Burmester, Redgum, Dan D'Agostino, Exposure, upper Denon models, upper Yamaha models, Accustic Arts, Sim Audio, Gato Audio, Plinius, among tube amplifiers: Leben, Audio Recearch, Air Tight, Conrad-Johnson, Acoustic Masterpiece, Copland. However, there are manufacturers worth noting that operate in both segments. This is McIntosh, Cary Audio Design. I especially want to mention Copland and Leben. As a rule, tube amplifiers for the most part have a low output power and, accordingly, it is most comfortable for them to work with highly sensitive acoustics. This does not apply to Copland, which is a kind of miracle of Scandinavian technology. He has, in my opinion, only advantages both in the nature of the sound and in the ability to control "heavy" acoustics. Leben has the shortest signal path, a completely surface-mounted installation without the use of printed circuit boards, and a selective element base. The depth (if we talk about the 300th ruler) is only 26 cm, and in terms of weight it is very heavy. And it is made in retro style, here many people follow the path of acquiring an amplifier first, and then acoustics.

From transistor - Dan D'Agostino. These amplifiers are truly marvels of sound reinforcement technology from a highly respected American manufacturer. A milled one-piece aluminum case, diffusion cooling of the amplifier, its numerous transistors, of which there are more than a dozen, in some amplifiers, a transformer that occupies about half of the case, of high quality, which ideally matches the amplifiers with the speaker systems. Made only by hand in the USA, these amplifiers, for the most part, have the so beloved arrows. The amplifiers have no overall negative feedback at all, so there is practically no intermodulation distortion. The products have tremendous dynamics and large bandwidth (1Hz - 200kHz (-1dB)). Up to 40 W amplifiers operate in class A. The housing is protected from electromagnetic and high-frequency interference. I had to listen to amplifiers of this manufacturer with Vienna acoustics, which are very demanding on the amplifying part, the result exceeded all expectations. The amplifiers also coped well with Focal Sopra, ATC, which are also not so easy to please)), especially they played well in conjunction with acoustic systems from the Estonian manufacturer Estelon.
