mono or stereo? (classe or ?)

Monoblocks do have advantages. If you are in love with the sound of the Classe, I say go for it. If you aren't, try the Krell KAV-250a. There are several rave reviews, the most recent in "The Perfect Vision" (they used music to judge this amp).

Yeah but are you talking about using the krell as mono blocks or just the one stereo amp that is twice as much? (I could probably just look in the classifieds to figure it out if the krell is in there but in case there isn't one in there could you let me know).

If you enjoy your classe, then more power to you. How much is double, $3000? I agree that the kav250 would be a good choice, but for a little bit more, you could look for a used fpb200 or vt100mkII. I was in your exact situation before; you can email me if you want to discuss further.

Sorry. I should have probably made my post more detailed. I could buy another classe ca-100 for $750 and use them as monos or would it be better to sell the one I have and buy one stereo amp for about $1500 used? What would give me the best sound? I would love to here the gear you guys mentioned but it's just to much. any other recommendations?

I have found, in general and at that price level, that if you use a 200w stereo amp, it will sound more effortless than two 100w bridged stereo amps. I bridged two bryston 3b's compared to one 4b and found the above to be true. It all depends on the sound you are trying to attain. Anyone, please correct me if I am misinformed.
