Unfortunatly I checked all that. I use banana plugs..all i did was unhook the Polks and plug in the M80's. I checked the ohms on the M80's..both were the same. The Onkyo just dose not like 4 ohm loads...pretty much. There is no other reason for the amp to shut down, It has never done that in 20 years...this is the first time. The amp puts out massive power...it shut down at maybe 50 watts. It just dose NOT like the load from the M80's.
So to make these work...I need a different amp.

The Adcom 555-II would be my first thought on this.

If the M80's didn't sound good for the first few min's i heard them....I would pack them back up. But they did. But i'm not about to blow my Onkyo to keep playing them. So i will look for a used Adcom 555 to replace it.

To say i'm not a happy camper at this point..would be an understatement. But if the amp can't cut it...not much else i can do.
