Pro-Ject Audio Systems
Pro-Ject Audio Systems are widely recognised as one of the finest turntable manufacturers in the world. Their mission is simply to produce the best sounding stereo analogue components at the most competitive prices possible. The current series spans a wide range of price points, with a variety of products targeted to key demographics or to accommodate the modern listener’s unique requirements.
In 2016, Pro-Ject marked their 25th anniversary year with the release of a turntable that combined traditional styling with modern technology; showing their innate ability to keep turntables fresh and interesting at a time when popularity of the vinyl format was at a previously unprecedented level. The Classic proudly sits in the middle of a multi-award winning range of turntables that manage to combine sound performance with the latest technologies and unrivalled style at every level.
Pro-Ject are also obsessed with the importance of stereo playback systems. With modern audio systems often bringing speakers either very close together or into a single enclosure, the real impact and importance of true hi-fi stereo is being lost. That’s why everything Pro-Ject create is made with pure stereo applications in mind; bringing back the true emotional importance of music to audio enthusiasts around the world.
Based in Vienna, Austria, all Pro-Ject Audio Systems turntables are made by a highly skilled workforce with great skill, care and attention in their central-European factory.

The Phono Box DS3 B is a dual-mono, fully discrete moving magnet and moving coil phono stage with balanced inputs and outputs. With a host of customisable features, it offers exceptional value for money and brings a notable upgrade to any mid-/high-end analogue hi-fi system.

The Pro-Ject design team took the decision to employ discrete circuitry in the Phono Box DS3 B. Discrete circuits involve no operational amplifiers (op-amps), and the result is a more neutral, natural, dynamic, and vivid sound. They are more complicated to put together and involve a greater variety of components, but the result when utilised in a well-organised electrical layout is a true high-end sound.

This philosophy for the best possible performance carries through to the variety of conveniently-placed features the Phono Box DS3 B has on offer. The phono stage can be connected to two turntables at the same time, and each input will save its previous settings in memory so the Impedance, Capacitance (for MM cartridges) and Gain will all be set as you switch between turntables. For MC cartridges, the continuously adjustable load-impedance dial on the front panel allows you to perfectly set the impedance to suit your cartridge and your ears.

As the Phono Box DS3 B is equipped with both balanced inputs and outputs, it is also part of Pro-Ject’s True Balanced Connections concept. By connecting to a turntable with a moving coil cartridge and using one of Pro-Ject’s balanced connection cables, your analogue system can benefit from increased dynamics, less noise and improved signal-to-noise ratios. Going true balanced is like hearing parts of your music that were not there before.

Elsewhere in the Phono Box DS3 B design, the fully-passive and discrete RIAA equalisation stage is optimised for absolute accuracy and signal integrity. Depending on the outputs you are using, this stage is then either directly fed to a fully discrete output stage (when using RCA outputs) or is connected to a fully discrete balancing stage for onward balanced connections.

The Phono Box DS3 B is finished in a steel chassis, covered by silver or black aluminium panels, for extreme rigidity and good electrical isolation. The neat minimalist aesthetic can be further enhanced by the addition of retro-inspired, magnetically installed wooden side panels (available separately). It also features an external power adapter, to keep the sensitive internal signals free from any interferences.

True Balanced Connections

The interconnect cable between a record player and a phono stage is prone to pick up noise on the way. That noise and interference can stem from a lot of unavoidable sources, such as household applicances, wi-fi and bluetooth devices, other power cables and audio amplifiers. Unshielded (i.e. RCA) interconnects can amplify the picked-up noise and make it audible through your speakers, interfering with the pure musical signal.

Balanced (typically XLR) cable connections double the wires carrying the musical signal – with one side inverted. In this case noise still gets picked up by both wires, but with one side reversed. When the signals are re-joined at the phono stage, the picked-up noise is cancelled out by the opposing signals. The benefit of this is a louder, cleaner musical signal that has doubled in size with almost no remaining noise.
