What stereo amp sounds better than digital monos?

Boulder might have something different and perhaps better to offer, but not cheap!

IS you pre-amp SS or tube?

If tube, any amp with 60K or greater input impedance might offer an improvement. I seem to recall that most of the amps you have had might not fall into that category for best match to a tube pre-amp but not certain.

IF a SS, you might have to drop more bucks to really upgrade. Not sure. Boulder is the one line I have heard that I would consider in this case.

Hi SunnyJim

I don't know if another kind of amp sounds better than another. It just may sound different or you may prefer one type of sound an amp makes in your system vs. another. Just my opinion. The reason I say that is I had the lower powered Red Dragon M100 monoblocks for a bit and a Hypex UcD based Class D amp and I found myself missing the sound of a McCormack DNA-1 Deluxe I had along with some other Class A amps.

I think out of the bunch you mentioned I say go with the McCormack or Odyssey. One audiophile some time ago suggested to me if you like the McCormack sound check out amps by Belles. Especially the Hot Rodded amps. Also what about the Emotiva XPA-1 monoblocks? Emotiva also has a 30 day return policy and pretty good customer service.

Krell may be of interest. I have the KAV-150a from 1999 and cannot seem to part with it even though it can sound harsh when pushed with low impedence speakers. my solution was to mate it with a small bookshelf design. Maybe something in the 250w area is a better idea if you like to crank it up and maintain great sound. Dont dismiss the star names in amplifier design cause they cost alot, amazing amps avail here because someone has the upgrade bug or just need a bigger unit. great amps go up for sale at 1/2 the cost you mention" just stay on the hunt and research as much as possible. Listen if you have the chance and remember quality over quantity when it comes to watts

I owned a pair of Adagios for a year or so. The amplifier that I liked best with them was the RedWine Audio Signature 30.2.

This amp. is a Tripath design, so not a class "D", and has much more warmth and flesh compared to class "D"'s.

I usually listen at 75dB average or so, and the RedWine could certainly play quite a bit louder than that without distortion, despite its lower power rating.
