What about the preamps ?,all this talk on amplifiers ...hooked up to what preamp ? makes a difference, I have 4 systems and a Mac C46/252 into a pair of B&W CM4 floor standing,nothing special, but a good quality speaker, and that combo sounds mighty fine, it doesn't "bowl" you over nor does it"bore" you to sleep.
But I can dramtically change the sound, by changing electronics, both tube and SS. As to Classe, can't comment,haven't heard any.
All I am saying is don't overlook pramps and sources for that matter
