Good grief, you've gotten a lot of suggestions. One more to add from the used market would be the Meitner STR 55 stereo amp or MTR 101 monos, very rich, tube-like amps without any of that treble that you so dislike. They can likely be updated by John Wright to state-of-the-art performance if you need, but sound great as-is. And they look great, small units in either mahogany or rosewood cases.
looking for a warm ss amp....
for my paradigm studio 40s. i hate a bright treblely sound! i currently use signal cables and a denon 3802 reciever. i have had many people tell me to go with bryston or anthem, but both have been out of my price range so far. which of these have a warmer sound? how would rotel or b&K amps sound with my speakers? they seem to cost much less. since i can only buy used, i really do not have the opportunity to audition the different amps. i will continue to use the denon as my pre-amp.
