PS - I think when Absolute Sound reviewed the Speakers they compared his amps to the 28B 's
Yes you're right about the 28's. When I was visiting with Roger at T.H.E. SHOW last January he was telling me that most people did not fully understand how much power the electrostats need to really shine. I told him that I was using the 28B's on my CLX's and he said "Ah, that's a great amp so you do understand."
Roger is a interesting guy and makes really good products.
