Mine is back to having the same power problems again after Emotiva "fixed" it. Its just not worth even sending it in again to me as I now have zero faith in the product holding up for any amount of time. I've got pieces of equipment in systems around the house that are five times older and have been subjected to very harsh environments that still work flawlessly. This one has been babied its entire life and could only manage to be functional for about a year and a half. Don't think I'll be buying another Emotiva/Sherbourn product.
Several persons with EXactly the same issue on the Same piece of gear, and now a Repeat Offender?

I know this is an old post, but add mine to the list. Sending it back today. Won't power on at all. Was also doing something very funky for the last several months. I'd set the speaker output levels manually and then turn it off for the night. The next day, they'd be resent to different levels. For example, what was once a center channel speaker set at 0 became a +4, or a left set to +4 magically went to 0 or to +8. Completely random and very weird.
Sorry, though. Mine is the Emotive Fusion 8100. Not a branded Sherbourn.
