I got an Onkyo SR-606 and some shitty 5.1 HTB speakers at the moment. My HDMI input\preset for my PS3 get some higher line noise than other presets\inputs on the receiver (ie cable/sat). I am going to try a different HDMI cables tomorrow when I rearrange my system. However, I am using component cables to my cable/sat input. I have read a few things regarding the receiver been plugged straight to wall instead of through a power/surge strip because of the better grounds. Any ideas?
