Thanks everyone for the helpful comments. Regarding the ground loop, I have all my equipment powered by the same dedicated circuit. I have also tried the Granite State Ground Control and a cheater plug with minimal effect. The only input to the HT receiver is my DVD player via HDMI. The HT receiver outputs to my Projector, also via HMDI, and to my 2ch preamp via RCA. Thanks for any other ideas!
2ch amp and HT receiver connected to same speakers
I listen to 95% music and 5% home theater. My 2ch system is a BAT pre and a Bryston amp, and I have an Integra receiver for theater. My BAT has a HT pass-through function, so that I can run my LR speakers off my Bryston amp. This setup causes a ground loop, however, and I've given up trying to eliminate it. So I wonder if I can connect both my 2ch amp and the LR outputs of my receiver to my speakers. Would this harm my amp (especially the Bryston)? Would it hurt the sound quality of my music? Thanks for any comments.
