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 CD Box RS & DAC Box RS Systen Review

Comments of Note:
“Switching to valves, and the bassline is bestowed with an extra degree of smoothness and warmth. I found that these differences enable the combo to be ‘matched’ to different music and recordings. The Beatles’ ‘Sergeant Pepper’ and Black Sabbath’s ‘Paranoid’ albums, for example, were made that little bit more enjoyable when heard through valves.”

“My 24/96 FLAC ‘rip’ of Miles Davis’ ‘Kind of Blue’ was heard with a presence and depth that was hard to distinguish from the original Columbia vinyl LP.”

Playing DSD64 files: AUN J Classic Orchestra – ‘Hachi-nin no hibiki (Eight People’s sounds)’
“The subtle tonal characters of instruments here were individually conveyed with precision, insight and finely-etched detail. Yet these definable elements all also came together as a cohesive and beautiful musical whole.”

“Clever and versatile.”

“FOR: - Flexible in terms of connectivity, format support and settings. – detail, focus and natural balance”
