For the Reference Monitors, you really don't need a lot of juice (but having extra never hurts)... I have found my various Tylers (I own both the Taylo Reference Monitors, and the original Linbrook Signature System -- and have owned the Linbrook Signature monitors) to be very revealing of amps, however. I have not tried Classe with them, but my best results so far have come after pairing them with CODA electronics. That combo definitely works for me, I am hopeful the Classe combo works for you.
Good luck,
