A highly comprehensive and affordable phono preamplifier, compatible with both moving coil (MC) and moving magnet (MM) capsules, it is distinguished by the combination of vacuum tubes with a double-mono balanced circuit topology, hence the "B" designation in its name. The second outstanding feature of this compact and refined electronic device, aimed at vinyl enthusiasts, is the use of discrete, audiophile-grade components and very low noise, with the aim of achieving the most natural and dynamic sound reproduction possible. The third crucial element of the Phono Tube Box DS3 B lies in the meticulous design of its RIAA stage, which processes the signal coming from the gain stage, also constructed entirely of discrete components.

Thanks to its internal architecture, the Pro-Ject features balanced inputs and outputs, managed by a dedicated stage, allowing you to take full advantage of the symmetrical connection to the associated line preamplifier or integrated amplifier. On the other hand, the unbalanced outputs (via RCA connectors) are also handled by their own circuitry, fed directly by the RIAA equalisation circuitry. The "practical" part of the Phono Tube Box DS3 B is particularly remarkable due to the wide range of adjustment options that guarantee full compatibility with most of the pick-up capsules available on the market.
