I just bi-amped my denon 3805...I like the sound much better now, but there is a hum coming from my speakers. I've read all the other posted questions and answers from other people, but I have yet to find someone who has figured out the problem. What is causing the hum, and how can I fix it ??
I've heard that was common with the 3805. There are threads somewhere that discuss it on this forum. For whatever reasons, the 3805 doesnt always like bi-amping, even though its bigger brother(5800 series) has no problem. Even though it's possible, Denon doesnt recommend biamping the 3805.
Good luck though, and hope you fix the bugs. Nice receiver......BTW.
