110 into 8ohms equates out to about 170W into 4ohms providing that spec isn't peak. The difference from 170 to 230 would be about 1-2 db, barely noticeable at all. This is why I look at a doubling of the 8ohm spec to really gain any improvement. So you would need an amp with 220W into 8 ohms this would give you ~300W into the M80s, a noticeable SPL increase and lots of headroom for them at lower volumes.

A Behringer ep2500 is 440$CDN for a 2 ch. So 440x2 (two amps) = 880$ +taxes + shipping + 4x RCA to XLR cables
since the signal is going from unbalanced to balanced XLR, there is a good chance of signal noises which requires an external device.
I'm always back to square one on this.. The Behringer A500 looked like a compromise but it looks unreliable from the hundred of posts I gathered..
