Art Audio Jota? I've just started using mine with a pair of 96db horn speakers and the experience so far is extremely good. I've been using the Jota for about 4 yrs now with upgraded tubes and I think it's marvelous. other things have come and gone but the Jota is a rock. If you can find one used they should cost around 4k, depending on tube set, condition, etc. The High Current version of the Jota puts out 24w per channel according to specs. Loudness has never been a problem, though that depends of course on the gain you have upstream of the amp. I've used the Jota mainly with Devore Silverbacks until recently, when I moved and switched to horns to accommodate a small(ish) listening room. I might try another amp with the new speakers but mainly out of curiosity, not need.
btw what are your speakers?
