And again last night, while flipping thru the DirecTV HD channels, a super loud buzz at around 1khz coming from left front only. Power off/on again with remote solved.
I agree that the sound is sweet but I'm beginning to think we're dealing with a major hardware flaw that no amount of firmware upgrades will fix.
At this point in time I'm wishing I'd spent the extra coin on an Adcom pre/pro.

I replaced a GTP 830 with the Outlaw, only because I wanted component and DVI switching, and in 3 years of owning it never experienced anything like this.
