and don't throw something stupid at me like. My speakers are not efficient enough cause 88db is pretty efficient for defteks. This 4 year old $350 dollar receiver shuts off at high volumes. I mean could it be the speakers? Could it be the tinsel leads probably hitting each other on the spider flex? I am not sure. It happens and shuts off mostly on explosions or loud impactful bursts. There have been times I left my receiver on all night through its 4 year life but that shouldn't be the reason that an output transistor is ****ting the bed. It is just a crap quality receiver I guess. I don't even like Denon now and I might just go Pioneer. I can't afford anything over 1000 but I just want a nice receiver with a ton of good features for music and blurays. I have my computer connected via HDMI to my samsung 40" nice TV I picked up less than 2 years ago.
