Great looking room. Nice and clean looking. I also like your equipment, being a Denon fan myself. I am bidding on a 3930ci on eBay and hope to win it at a reasonable price (SACD,DVD Audio, here I come).
My only suggestions would be to give your speakers more breathing room. I would move the equipment rack to the left side wall or behind the couch somewhere.
Second, your couch seems to be placed awefully close to the center of the room. Not a good place to sit acoustically as it is usually a null area.
Third, I would try to get the center speaker closer to ear level. Although a lot of center channel speakers sound better standing on end, I would think this may be negated by the increase in phase shift due to its current orientation and higher placement.
Not easy issues to overcome sometimes due to space limitations but defineately food for thought!!
Keep up the good work and keep us posted on your progress. Lots of front projection nuts around here to provide encouragement.
