Hi Julian, you didn't say what your budget was for this or if you want new or second hand.
You could do a lot worse than try the Monarchy Audio SM-70 or SM-70 Pro. I have both and they sound great, rather similar to earlier Krell amps and these too are pure Class A, they are every bit as good in their own way as any valve amp I've owned. They're stunning value for money and really have to be heard to appreciate what they can do.
As for the Electrocompaniet amps, I've heard some of the older models and always thought they sounded excellent.
Another make I'd be looking at is Lavardin, not that easy to track down used, but very fine sounding!
It is impossible for anything digital to sound analogue, because it isn't analogue!
