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.
