A very complete and affordable phono preamplifier compatible with moving coil (MC) and moving magnet (MM) capsules, which stands out for combining vacuum tubes with a completely dual monophonic and balanced circuit topology (hence the “B” in its name ).

The second fundamental characteristic of this compact and refined electronics intended for vinyl record enthusiasts is the use of discrete components (that is, individual and therefore not integrated into “chips”) of audiophile grade and very low noise, in order to to obtain a sound that is as natural and dynamic as possible.

The third key element of the Phono Tube Box DS3 B has to do with the very careful design of its RIAA stage, responsible for processing the signal coming from the gain stage and also executed 100% with discrete components.

As a consequence of its internal architecture, the Pro-Ject includes balanced inputs and outputs that are entrusted to a dedicated stage, allowing it to benefit once again from the symmetrical connection, in this case to the associated line preamplifier or integrated amplifier.

As for the unbalanced outputs (via RCA connectors), they are also treated by their own circuitry, which is fed directly by the RIAA equalization circuitry.

The “practical” part of the Phono Tube Box DS3 B would have to be described as spectacular, as a result of the generosity of adjustment options that ensure full compatibility with the vast majority of pickup capsules available on the market.
