I understand your frustration. I've had a couple of 970's and both went back to Outlaw for a 'fix'. While it is a problem their customer service is great. The latest one I have was returned after a fix but has been unopened in the closet since I got an Onkyo 886. I'm probably going to open it up and put in back in my system this week to see if it's ok, especially since I'm planning on selling my 886. Hopefully the 'fix' worked. It's still under warranty so I can send it back again if there's still an issue.
