Well, looks like the trusty 990 is back in it's place until I can get an electrician to come out to the house. I did exactly like I said I was going to do, went home and instead of hooking up one peice of gear at a time I ended up hooking all the gear up and then ran the extension cord from the projector to the HTS5100 which is where the rest of the gear is hooked up and low and behold, the buzz/hum is back. The noise doesn't seem to be as loud as before but it's there and it drives me crazy, it seemed to be more noticable when the Elite was set to "tuner" mode, but it's there. My father has a neighbor that he's been friends with for 20+ years which is a master electrician so I'm hoping to get in touch with him to see if I can't get him to come by the house and take a look at what I have going on. On another note, I did however deal with the buzz/hum long enough to fire up Casino Royale on Blu-Ray and run threw some chapters for about 15 minutes or more to see if the Elite would even be something I may be interested inn and I must say, I definately need to get the buzz/hum fixed so I can do some more critical listening, from what I heard, the Elite/7700 combo sounded pretty impressive.
