True Balanced Connection, Within Reach
The Pro-Ject Phono Box DS3-B brings high-end phono performance to a more accessible price without sacrificing the build quality and musical character Pro-Ject is known for. It takes some of the standout features of the RS range—especially the new True Balanced Connection—and packages them into a compact, well-engineered chassis suited for real listening rooms.
High-End Features and Limitless Loading Options
At the heart of the DS3-B is a true fully balanced gain stage design. Whether you connect a turntable through single-ended RCA or balanced XLR, the symmetrical gain stage can optimize signal-to-noise ratio before the signal reaches the equalisation stage. The chassis combines steel rigidity with aluminum panels for better isolation from interference, vibration, and the electrical noise common in modern households.
Dual Turntable Inputs with Memory
You can connect up to two turntables at the same time, and each input stores its own settings in memory. That makes switching between decks fast and accurate, whether you are moving from a main listening turntable to a secondary vintage or DJ-oriented table. It is one of the most practical reasons to choose the DS3-B over a basic single-input phono stage.
Continuously Variable Impedance Control
Load impedance can be set continuously via a potentiometer—a system invented by Pro-Ject Audio Systems—so you can adjust loading during playback and assess the sonic result in real time. This makes cartridge matching more intuitive than ordinary stepped-impedance switches and helps you find the setting that sounds best with your specific turntable, cartridge, and cable combination.
True Balanced Connection
Cartridges are balanced signal transducers by nature. The DS3-B takes advantage of that through its True Balanced Connection design. While MM cartridges are commonly wired for single-ended output, MC cartridges can access a more complete balanced signal path. Together with Pro-Ject’s True Balanced Connection cables, the DS3-B unlocks cleaner signal extraction, lower noise, and better rejection of interference from household appliances, Wi-Fi, power cables, and audio amplifiers.
Fully Discrete Audio Circuitry
The DS3-B uses fully discrete audio circuitry rather than relying entirely on op-amps. Discrete circuits are built from individual electronic components, and Pro-Ject’s engineering suggests this approach tends to sound more neutral, dynamic, and musically engaging. The passive RIAA equalisation is entirely split, which supports better impedance matching and closer adherence to the ideal RIAA curve.
Expandable Design
Magnetic wooden side panels are available separately, so you can customize the look of the unit to match your system or room. This reflects the broader product philosophy: high performance, flexible setup, and user-friendly design.
Best For
- Dual-turntable audiophile systems
- Upgrading from entry-level or non-balanced phono stages
- MC cartridge owners interested in balanced playback
- Listeners who want real-time impedance adjustment without complicated tools
If you want balanced phono performance, dual inputs, and Pro-Ject’s cartridge-matching flexibility in one compact box, the Phono Box DS3-B is one of the most practical next steps from stereo playback to serious vinyl listening.
