I have a friend who is using the Red Wine Audio Signature 30.2 to drive a pair of ESL 57s and I have never heard the 57s sound so good and he has tried many amps - tubed and solid state, some costing many times the price. He saw this comment about the combo in this review

and decided to try it out and was equally amazed and so was I. Only 30 watts per channel, but lots of current from the sealed lead acid batteries and the strange impedance of the 57s does not seems to bother the 30.2.
The sound is warm rich and tube like but with very accurate bass response and nice dynamic range. I also recently received my 30.2 and am equally impressed, but I don't run Quads but I am thinking of getting a pair of Waynes ESL 57s now! FWIW...
