I've heard many, and my favorite is the George Wright 3.5 monoblocks, which must be paired with his preamp. For about $2200 new (and maybe $1500 used), they are an astounding combination. I would suggest that if you go this route, plan on some tube rolling, though you don't have to kill the pocketbook to get an absolutely glorious sound. Like I said, I've heard many SET amps, including those costing more than ten times the price, and nothing sounds as lifelike and airy as this setup.
Good luck with your search. Should be fun.
P.S.--I have these paired with a set of 1977 Klipsch La Scala's, which have been rewired with all silver wire.
