Pro-Ject Phono Box DS3 B and S3 B phono stages: balanced discrete models with smooth impedance adjustment

Pro-Ject Phono Box DS3 B and S3 B phono stages

The "B" in the names of two Pro-Ject phono stages, Phono Box DS3 B and Phono Box S3 B, means "balanced". Both phono stages are assembled according to a symmetrical scheme, and this is a serious change for Pro-Ject: until now, this ideology was used only by the older RS ​​models in the line. Together, these models will make up the "True Balanced Connection" line of components, which will be complemented by the X8 turntable with a matching branded cable. 
The older phono stage of the two, the Phono Box DS3 B High End, takes a lot of the circuitry from the much more expensive RS 2 , in particular the signature smooth impedance adjustment feature. The potentiometer is displayed on the front panel. In addition, DS3 B received control trigger connections - input and output. The younger novelty, Phono Box S3 B, does not have them. Both phono stages are powered by an external linear power supply.Otherwise, the two models are similar. Both have balanced XLR inputs and outputs, complemented by a 5-pin mini XLR (possibility to connect an amplifier with one cable). It is also possible to work with two players at the same time. The parameters for each input are stored in memory.Both phono stages use a passive, discrete RIAA equalization circuit, which Pro-Ject claims has been re-engineered. There are no operational amplifiers in the circuits. Ultra-low input parameters, such as 50pF or 10 ohms, will allow new products to work, for example, with exotic MC cartridges.
