You're right, the volume level was very quiet, which was quite disturbing. I was experiencing massive amounts of distortion, which I took to mean the amp was clipping. It's possible something else was wrong, though I have no equipment to test. Let me know if there is something else I can do in that regard.
I hooked up my 777 tonight and it's running along fine like it always did, so I guess you could say the problem is corrected with what I have now
I don't have my M80's hooked up at this time though as the 777 isn't rated to handle a 4 ohm load.
