Part of Complete Upgrade
Monday, 15 June 2015  | 

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 Team

I 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.
