What stereo amp sounds better than digital monos?


I want to replace a pair of Red Dragon digital mono blocks with an excellent SS stereo amp of approx 150 RMS.I have Acoustic Zen Adagios speakers

I am not interested in tube amps or tube rolling. Need input and/or recommnedations. I CANNOT afford $5000 ARC, Levinson, Krell or other super high end basic power amp. In the past, have considered Odyssey Stratos SE, McCormack DNA-1 upgraded to "REV B" or "REV A" level; also, the better Conrad Johnson SS power amps. Thank you.

Yes, me to in regards to expensive amps like boulder.

I would still recommend giving them a listen. I have not heard them on many systems but the struck me as unique sounding and possibly quite good, a useful reference. You might then be able to find something similar and more affordable if that sound floats your boat. I'm thinking something along the bryston or mccormick line maybe.
To Daniel, I have a Bel Canto PRe-3 pre-amp line stage which is excellent. I believe it has balanced outputs...amd also has RCA outputs for the amp. I am not sure what you mean by a "truly balanced pre-amp" I assume that the Rowland amp like Sim Audio amps sound best only with balanced inputs/outputs.

To Mapman, Excellent suggestion. However there are no Boulder dealer in Honolulu; There is a Soulution dealer, but I don't relish lifting 120lbs small frig of an amp or its $45,000 price tag. Nevertheless, a good suggestion. It look like a modded McCormack is my future. Hopefully, it sounds outstanding as so many claim and not like an Adcom, Dynaco or BK amps of some years ago. Thanks!!!
" Can't afford $5000 super high end basic amp " LOL. Thats a good one, I thought $5000 was in the lower mid category.
Good luck. Mccormack is a very reasonable choice.

My strategy is always to listen a lot and listen to the best whenever possible, then buy what I can afford.
Sunnyjim, I'm curious. I've been considering getting a pair of Red Dragon M-500s. What is it in your Red Dragons that makes you want to move on?
