All, an update:

I just tried connecting my old Denon receiver as the amp, using my 950 as the pre-amp. Got sound! So it seems my 755 is fried and 950 is probably OK.

I spoke with Scott at Outlaw today and they are setting up a return authorization for the amp.

Lena, interesting that you say that power surges can cause degradation of the Panamax-- so there's no way of knowing if it is working or not? Seems like there should be a way to determine the status of the Panamax without sending it in. So what do I do with my Panamax?

Power outages are rare in my neighborhood. But all it takes is one I guess. What would you suggest for a surge protector, without having to cash in my 401k?

I still think it's just as likely the surge protector works fine and the amp had an existing problem.

Also every other electronic component in my house works fine, including all of the other components plugged into the Panamax.
