Finally home to check all those ideas......
Changed the receiver to "large" on the fronts and small on center.
Center is -2.5 along with the mains.
Cranked up a meatloaf concert from Australia and worked my way to +1.5 lasted 3 minutes.
SHUTDOWN
Changed settings to all "small" and ran it at +1.0 for 20 minutes with NO shutdown
All wires across the front were replaced and re-connected before the experiment began.
Spend some time this weekend to be sure, but my final thoughts are the receiver
Can't have the mains set to large and crank it into the +1 to +5 range
Just weird because my older elite could handle it.
Cheers
That's good news. Your initial findings say you don't need to spend any additional money on external amps.
I think the M60's when played full range the midrange tries to play down as low and loud (as it possibly can) along with the bass drivers and your receiver doesn't like that at higher output.
