Four specific characteristics make this a true high-end preamplifier: 1. Fully balanced double mono design 2.class-A circuitry with no negative feedback 3. Tube output stage 4. Separate power supply as an upgrade option for further improved sound quality.
Pre Box RS offers 3-dimensional sound-staging, perfect micro dynamics and ultimate resolution combined with flexibility to use XLR and RCA sources. Perfectly combined with Pro-Ject Amp Box RS amplifiers, Pre Box RS will give pure sound experience, that the real audiophile is looking for. Pre Box RS utilises a luxury casing, that is available in silver or black finish.
I have this with the add-on power supply and improved cable. An upgrade to my system meant I needed to introduce a pre-amp between my Dac and my active speakers to improve impedance matching. This does the job very well without adding or subtracting anything - it is impressively transparent.

This is me two months into complete upgrade to the Pro-Ject "RS Line". I Purchased the mono amp boxes, pre-box, phono box, headbox and stream box.Straight away the sound stage that was present by these little project boxes was very very impressive. With the valve stages there is a warm sound presented with lots of depth and detail which suits my listening preference to a "T". The build quality is excellent and the size was a big plus point from an aesthetics and space perspective.There was "out of the box issue" with the Headbox but a quick email to the guys at Analogue Seduction and it was sorted straight away with an excellent no hassle/quibble replacement service. Great Service from the Analogue Seduction TeamI would have no reluctance in recommending the Pro-ject boxes to anyone. And anyone who has heard them is always left impressed. As I said, I am now 2 months in and they continue to surprise and delight.
