Hi,
You will be amazed by the bass quality and output of the M80. Under a limitless power or close; they can be shockingly good. I clearly remember when I first powered them with the Axiom A1400-8; I was sure that I had my sunbwoofer on. I had to walk to it to be sure that it was off. And, at that time, the A1400-8 was replacing a powerful refernce Mark Levinson No 23.5 (400 watts per channel at 4 Ohms); never under-estimate the effect of abundant clean power.
