In my bedroom my amplifier keeps shutting down. I've tried 6 different receivers (of different models and brands) and they all have this problem. Basically after idling for about 3-4 hours or so, they go into protection mode and shut down randomly. Sometimes this happens during playback, but most of the time this happens while just idling. I tried using an Emotiva CMX-2 but I'm not sure how much it's helped--it's eliminated any toiroidal amp hum I previously had, but I still get random shutdowns, so I think it's reduced most of the DC offset but not all of it. The receivers are all sitting out in the open and room temperature is quite low so its not a thermal issue.
I'm thinking of maybe getting another DC offset blocker and connecting it to the CMX-2 before connecting to the receiver. I'm wondering would that actually improve the DC offset blocking ability by stacking DC blocking devices, or is it like sunglasses where you actually get less UV protection when you stack them (or even make no difference)?
