My Denon 3802 has been acting strangely for a while, and now I think it's about to go belly-up. What happens is that it shuts itself off (into standby mode) whenever I play anything too loud. I don't mean HTF-subscriber 'too loud', I mean your-mom type of 'too loud'. In other words, with any components, if I go above a "normal" listening volume, the thing goes click and turns off. My assumption is that the amplifiers are sickly. If that's indeed the diagnosis, could I just buy myself a 5-channel amp and use the Denon as a pre-amp (as a slow move towards separates)? In other words, if it's a volume problem, should it continue to be a problem if all of the amplification is coming from a separate amplifier? Thoughts?
