If money is no object, perhaps the ESL amp is for you. For me, the PS Audio 200CX is the ticket, I have Acoustat Spectra 3300's. I am about to bi-amp them as the PS does run out of steam at VERY high SPL's. Perhaps I should just sit colser to them. :-)But for $500-$600 used, the PS Audio 200CX is hard to beat.
