I've heard that Pioneers have a harder time powering the M80's but so far I haven't heard any testimonials of anyone with any of the Elite series. I have the cheapest of the Elite AVR's and I'm only powering M22's and a W100 with it and it barely gets warm. But since I haven't tried the M80's I can't say for sure.
