I will first explain my setup.
I currently have a 5.1 setup
LSi 15 FL/FR
Wharfedale Diamond 10.1 RL/RR
Denon AVR 2310CI driving the center, RR, and RL And FL/FR pre-outs connected to NAD275BEE which us driving the LSi 15s
When I wired everything I and when there is no input source I do not hear anything which is normal. However, once I choose a source like for example my htpc connected over hdmi I get a hiss sound when nothing is playing, when its idle there is no hiss sound.
When I play a song it masks the noise but not fully. It is annoying and I am bit worried that they could be damaged.
Also I tried Audyssey on Denon but I got out of phase for L/R, is it my room or the speakers has inverted phase? Also SPL with Avia or Audyssey for best sounding setup?
Appreciate any advice you can offer.
