Product Summary
The Pro-Ject Phono Box DS3 B is a high-performance phono stage designed for customers who want a serious step up in vinyl replay quality, with the added advantage of Pro-Ject’s True Balanced connection concept. It is built for more ambitious analogue systems, giving you a cleaner, more refined and more flexible foundation than entry-level phono stages can usually provide.
A big part of its appeal is the way it combines strong engineering with real cartridge-matching flexibility. The Phono Box DS3 B uses a fully discrete dual mono design and offers both balanced and single-ended inputs and outputs, making it suitable for conventional turntable setups as well as more advanced balanced systems. Adjustable gain, capacitance and impedance settings also make it easier to fine-tune the phono stage to suit a wide range of moving magnet and moving coil cartridges.
It is also designed to be easy to live with in a serious hi-fi system. Front-panel controls make setup adjustments more convenient than hidden switch designs, while the solid aluminium casework helps shield the sensitive circuitry from outside interference. For customers wanting a phono stage with genuine upgrade potential, lower-noise balanced capability and a more confident, more revealing sound, the Phono Box DS3 B is an outstanding choice.
