HOW TO CHOOSE A SOUND AMPLIFIER?
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.
