Refined 30-60 watt Tube amp

You can find information on the Viva line at Walker Audio. I have no interest in the company. They use a variety of output tubes but the 845 tube Aurora is the most powerful at only 36wpc, however be careful of simple power ratings. Its a very expensive amp. If you've got that kind of money to burn check out the Cary 211. Refined is a tough adjective to define. I am surprised that you thought the BAT was "too" powerful, I like their sound. If you meant too full sounding then consider an SET or OTL as mentioned. I agree that the Atmasphere M60 is about as pure as it gets. The possibilities are innumerable- good luck

Has anyone heard the Graaf GM20 OTL? I have heard good things about it. Also, how about border patrol?
Mechans - What is it that you like about the cary 211?

I also checked out the deHavilland audio gear and it looks very promising. Where can i hear this stuff around NYC? Again thanks for everything

A used pair Antique Sound labs 1009. Employs a pair of 845's at 60 watts/channel.

You might look at the Canary line of 300B p-p amps, especially the CA-301 stereo amp. I have the big brother monos, the CA-339, and I'm extremely impressed. 22 wpc, but the lower output impedance means thay'll drive 6 ohm speakers better than your average SET. The dynamics and purity of tone of these amps is really something to hear.
