Pro-Ject Audio Systems

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.

S2-Line
The Pre Box S2 Digital is an ultra-modern DAC, pre-amplifier and headphone amplifier, engineered inside a compact, beautifully made chassis; representing luxury high-end audio performance at an astonishing price. Entering the market as the first product of the S2 Line from Box Design by Pro-Ject Audio Systems, the Pre Box S2 Digital is designed to accomodate even the most demanding digital audio enthusiasts.
Built around the high-end ESS Sabre ESS9038Pro DAC chip, the Pre Box S2 Digital is capable of converting Hi-Res Audio signals up-to 32-bit / 768kHz PCM or DSD512 (DoP) via its Type-B USB port. The DAC has also been configured to unfold the very latest MQA audio files and is certified Roon Ready. Via the additional Coaxial and Optical inputs, the DAC chip is configured to handle up-to 24-bit / 192kHz data from external digital transports. Where the Pre Box S2 Digital enters a league of its own is in the advanced technologies that have been applied to achieve a near-perfect technical performance.
Pro-Ject's proprietary Optimum Transient Digital Filter and complimentary clock circuitry design allows the Pre Box S2 Digital to manage jitter down as low as 100 Femtoseconds, ensuring the tightest and most capable audio performance possible. The sound can then be tailored to suit any listener's preference thanks to the seven built-in digital filters
The internal layout of the Pre Box S2 Digital is reminiscent of far more expensive designs. Through the clever use of polymer capacitors and thin-film miniMELF resistors it was possible to fit all this technology into such a small chassis. Elsewhere, industry-first innovations in the dual-regulator architecture makes sure the sound performance does justice to the true high-end formats you can play through the DAC.
Operation of the Pre Box S2 Digital is simple. Through the built-in operating system, or using the optional remote control, it's possible to change filters, attenuate volume and have basic transport controls over music played via USB (Ply/Pause, Forward/Rewind).

"Pro-Ject’s Pre Box S2 Digital offers a wealth of audiophile tweakery but its emphasis on USB ties it primarily – but not exclusively – to desktop and laptop PCs. On the other hand, USB hook-up means the S2 is still a portable option for laptop users, and it doesn’t need a battery. For the price, its sound performance is impeccable, combining clarity and precision with an attractive warmth and impressive sense of space." |
