There was a problem with the protection circuit cutting in on the M80s. Emo offered a mod when you bought it to remedy the issue but as you say I believe it’s been taken care up across their whole line now.

My personal preference with 3 large front speakers is 3 monoblocks. That way if one goes out you can still run stereo with the amps while waiting for the third to be repaired or replaced. JMO
