I have heard them twice at a dealer frined of mine here in New Jersey. The ones I heard where the $7K models, forget the name. He had the Atma mono blocks on them and then these little digitla amps 100 wpc called the flying moles ($700 for the pair) and I have to say that those little SS digi amps were exceptional at lower volumes. Warmer than the tubes. The speakers probably won't be optimal with low powered SET amps if you like some volume but overall they are extremely musical, easy to place, and have a very nice sound.
Happy Listening.
