I designed the cabinets for the house we built from scratch.
The benefit to buying the 57" Hitachi is that they have pdf's of each TV with umpteen different measurents - huge asset as the roof was sloped at the rear - but so is the TV.
Rack was from avrack in Sherwood Park (may be out of business now as the site was down last time I checked). Awesome quality and Canadian (Albertan for that matter).
The Russound whole house amp is on the bottom.
I just retired my old Sony DVD player in favour of a new LG DV7832 with plays VCD/SVCD/DVDR/JPEG.
Audio is Energy Take 5's with 10" sub. Room is wired for 6.1 but I need a new amp.
This room took lots of planning. 8)
Waiting for the right time for the new Motorola 6208 HD PVR (ie "on sale")
