A great opportunity for someone to experience this excellent DIY Preamp. It uses the latest Stereo Coffee LDR boards and incorporates a separate fully modded clone Musical Fidelity X-10D valve buffer, using a pair of 6922 valves and mundorf caps. Valves inside are a pair of Matsushitas (my personal favourite after some rolling).

It was built according to my requirements by a friend with 35+ years of audio engineering experience.

It has been wired up so you can connect it any which way you like, so you can use it as a straight LDR passive, a straight MF X-10D buffer or (my preferred way of using it) with the LDR first followed by the buffer, plus tube rolling opportunities too, so a bit of a tweakers dream.

I prefer putting the buffer after the passive as this resolves impedance matching issues and drives longer cable lengths from your source, whilst also adding a dose of bass slam and punch, with just a little touch of valve magic, but YMMV.

The buffer runs in pure Class A I believe and has an output impedance of not a lot, so makes for an easy load for your amp/speakers.

It has 3 inputs (selected from the rear) and the volume is remote controlled.

Only selling because I am heading into the 'no preamp' route in one of my systems. I have another one of these I'm still using in my other system.

All told, it has around £600 worth of parts in it and is only 1 year old, but now selling at the bargain price of £400 including free delivery (UK only).

Ideally collection from near Melton Mowbray but will consider delivery at buyer's risk. Obviously being a DIY job it doesn't have official packaging, but if sending I would of course get it packaged up safely.

Any questions, just PM me.

No interest in this yet, which is a bit surprising.

I have seen completed Stereo Coffee LDR preamps go for around the £500 mark just on their own. An X-10D modded to this kind of spec is probably another £250's worth (the mundorf caps plus valves alone cost nearly £200).

Also willing to chuck in some barely used Electro-Harmonix gold pin 6922 tubes for some added tube rolling fun.

If you can find a better sounding preamp for under £2k I'd be interested to hear it!

Stupid question?
does it require a short RCA lead to pass the LDR signal into the buffer? I am a little unclear on the labelling
and approx dimensions?
