Is there any reason why Audio/Video equipment cannot be installed in a closet, i.e. at the top of a hat/coat type small closet. I would like to install a plasma over a new fireplace I am designing but have nowhere to install my 921, Denon receiver and dvd player.' I'll install everything with infrared repeaters on it. I don't think the ventilation or lack of is any different that being hidden away in a tv stand with glass doors on it. Any opinions?
