I am using an older classic Classe power amp (DR-9) to drive the M80's. The amp can drive any speakers made, I use to drive Apogee panel speakers (2ohms). But I could easily drive them with my Denon 4800 (currently used as a pre/pro) also. The M80 are a great set of speakers, they have replaced my Mirage M3's. Man they are so good I am using two sets of cables for biwiring them that cost over $4500CDN. I know Axiom dont really think there is a diff in speaker cables, but I tried a lot and there is diff's. If you want a decent reciever to drive the M80's try the new Denon 4802 since the 4800 is discountinued. I mean the M80's are the cheapest ... rephrased that... lowest cost item I got in my main system. Also have the the VP150 center (Def Tech BP6B as rears and 3 subs - 2 8in and a 15 in). Also using M3 and M1 in another system. Axioms are the best buys outthere for speakers, esp in Canada.
