corelone,
As I stated in my post (which looks kinda confusing I guess), I got all my video cables thru monoprice.com, and my in-wall speaker wire from Bluejeanscable.com. The Belden greyjacket 12guage in-wall rated speaker wire.
I did not use GG, it was not in my budget. Honestly, even with reference level movies, the drywalled ceiling and walls stop alot of sound, about 30 STC worth. My wife can sleep 2 floors above the theatre and not hear anything...ocasionally if I am REALLY pumping it while gaming (>80db) some of the stuff in our on-suite bathroom rattles a bit 2 floors up...stinkin' EP500
