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.

Pro-Ject Audio Systems (project) Tube Box S2 MM/MC Phono Stage
Free Gift

  • Sale
  • Regular price £325.00


The Tube Box S2 is a premium phono stage for both Moving Magnet (MM) and Moving Coil (MC) cartridges. In order to achieve the best sound possible, it's become Pro-Ject's first product to feature a discrete circuit design without any operational amplifiers (op-amps).

The Tube Box S2 delivers a relaxed audio performance with lush mids in a full and enveloping sound stage, just like far more expensive pure-valve phono stages are capable of. Thanks to the built-in adjustable gain, capacitance, impedance and subsonic filter settings, it's possible to tune the device to perfectly complement almost any modern MM or MC cartridge. It's also possible to tune the sound further, as the Tube Box S2 is Pro-Ject's first ever product designed for the valves to be replacable - allowing for tube rolling or sound shaping. 

The new S2 casing is a big additional asset to the design, as not only does it deliver the highest visual appeal, but it is also sturdy enough to protect the internal circuitry against unwanted interferences and vibrations, which can cause unpleasant listening experiences. The Tube Box S2 also benefits from protective cages around the valves - inspired by the superior Tube Box DS2 design

Inspired by high-end designs but available for a very appealing price, the Tube Box S2 is a real audiophile bargain.
