Building a 65 in widescreen into the wall? Sounds like a lot of trouble to go to for a clean look. Do you have control of the ambient light in the room? If so why not go BIG SCREEN. W/ a digital projector? W/ a retractable screen your video system goes awat when not in use.

My philosophy is BIGGER is BETTER.

p.s. I disagree w/ an earlier comment about components. IMHO buy the best speakers you can afford. Then as you upgrade your components. (and you will) Your speaker performance w/ improve. Even a Levinson setup w/ krell monoblocs w/ sound bad on bad speakers.

Just my 2c.
