At the risk of stating the obvious, they should have a high, relatively flat impedence curve for the most part, although as others noted, they are reported to mate well with Quads. Also Soundlabs and Magnapans, IIRC. I have used them successfully with Merlins, Hornings, and now with a DIY pair of open baffles with field coil mid/tweet and conventional mid/low bass units. From personal experience, if you have the room, they are fantastic with the Classic Audio speakers, being able to reproduce live SPL rock music in a very large room with the M60s.. If you want to get an opinion about how they mate with a particular speaker, you should ping Ralph (Atmasphere screen name), if he doesn't show up here on his own. You will get an honest opinion with, IMO, no marketing hype.
Recommended Speaker List for Atma-Sphere OTL Amplifiers.
OK, I am not sure how many times this has been disscused but the information is found all over the forum. I would possible love to compile a list here.
I personally own the Classic Audio Loudspeakers T1.5
I am now looking to build a second room with the M60 Mono Blocks and MP-3 Pre-amp.
Would love fellow audiogon memebers posting any feedback with speakers they have used with these Amazing OTL sounding Amplifiers.
