Tube Mono-Block Recommendation

I like the Amps, to be fast, Accurate and musical as possible. Giving me close to Transistor Amp Clarity

That should be no problem :)

Looking at the specs you will want something with at least 100watts in most rooms.

So- how big is your room, how lively is it and how loud do you like to play the stereo?

If you are dealing with tube amplifiers, its better to rate the speaker in terms of efficiency rather than sensitivity. So that number is 93 db, a moderate efficiency and why in most cases 100 watts (or slightly more) ought to do the job, unless you have a large room or it is particularly dead.

Dragon_vibe, I agree, in a room like that you will need more power.

Our MA-2s might suit. They make about 220 watts and are very fast (600V/usec).

Dragon_vibe, It is true that our amps run kind of hot. But that is not because they are OTLs, it has to do with their being class A, something that you indicated you wanted in your OP. If you want 200-some watts and class A, you are going to get some heat, but it will also sound better, all other variables being equal.

Reliability is why we are still here 37 years on.
