Amp Suggestions

With that setup I'd go tubes all through. The Jadis 30, as suggested above has not enough power. Within your price range the Antique Sound Lab Hurricane monos,($4400 new) which HP raved about in TAS, would be ideal, I find. Don't go for less.....

Parasound Halo, McCormack 500, Pass X-250 are all very good choices as is the Edge amps.

My vote goes for Classe but consider a tube preamp or D/A, I ended up with a tube D/A over the tube preamp, also you may consider bi-amping which helped for me as the system is more musical, synergy...
Happy Listening!

Atma-sphere OTL. Very dimensional and rich. The antithesis of lean. No grain. Somewhat soft on the bottom (except MA-2) but not lacking in quantity. Extremely musical sounding. There are more but I could not resist mentioning this one.

My disclaimer: I'm not crazy about tube amps.

I think that there is no way that you could go wrong with Classe or Levinson. I also think that Jsawhitlock's suggestion that you consider a tube preamp is very interesting.

Good luck!
