Golden oldie!
16 June 2023  | 

Purchased because it was one of the few pre-amps that really suited my system! I have two sources that are fitted with xlr's and there aren't many pre-amps that will accept more than one. This is an NOS Pro-Ject model with 2 x 6922 output valves; again, this is exactly what I was looking for. The output voltage swing is perfect for driving my Hypex Nilai mono-blocks. The sound is very clean, neutral but not bland. HF is sweet with no digital screech, mids smooth and lucid whilst the low end is tight, deep and "textural" (if that's a word)! It's small form factor is a plus point for me too! An alround great piece of kit for the money! Analogue Seduction delivered what they promised on time and at a decent price! Well done guys!

impressively transparent

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.

Part of Complete Upgrade
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.
