Amp Recommendations for AZ Crescendo

Why not see what you think about the amp you have first.
What preamp would be in front of the tube amp?

In atleast 2 audio shows I know of; the creator/designer of AZ speakers matched them with Triode Corp tube amps and they sounds fantastic.

So I guess you cannot go wrong with that.

Congrats on the Crescendos. They are superb - about the very best I've heard. I suggest you contact Steve at Sounds of Silence, he's a dealer for AZ. I've heard the Crescendos several times at SOS with a few different amps. I'm sure Steve can point you in the right direction.

Congrats on the Crescendos. I've heard them at my local AZ dealer, here in NH and they are superb, but will need about 700 hours to sound their best. I've heard these with Atma-Sphere and Kondo amplification and both were excellent. Contact Steve Klein at Sounds of Silence for his experience pairing with tube amps.

Great speaker but they do require the right tube amp to sound their best; IMHO your Modwright will not be the best choice.
I too was at SOS last week, wonderful set-up, you should definetly contact them, you can not go wrong with their suggestions.
