Hi Eric45,

A big power amp like the ADA1500 will allow you to play your M80s very loud without any distortion. There is always a limit and always a way to push the limit higher right up until you end up with LFR1100s driven with a dedicated ADA1500-2 amplifier per speaker. But having lived with M80s driven with an ADA1500 amplifier, I can say with confidence you will be blown away.
