How timely your question is. I just picked up a pair of 3.5rs and bought a Classe CA-200 to mate with them. The Classe is an extremely nice sounding amp. It is very neutral and does not really sound like tubes or SS, it just sounds natural. And this is coming from a dyed in the wool tube fanatic. It is very powerful and drives the Maggies with no trouble whatsoever. I can't begin to tell you how much I love this combination. Highly recommended.
