Needed a personal retreat for music and movies so we converted the den into a dedicated theater and listening room. First thing was to enclose the room. Doorway and the plain wall next to it are new. Then cut into the wall to create the equipment rack. The wall backed up to a guest coat closet. This provides easy walk-in access to the back of the equipment through the closet. Installed dedicated power supply connected to Wattgate power outlet. Added carpeting and draperies along with Echo Busters to tame the acoustics of the room. Thanks to Dan Harmon at Dedicated Audio in Phoenix for so much great help, advice and service.
I made the upgrade from the Krell showcase amp to the Krell KAV-2250 2x250 and it has made the biggest improvement in my music listening. I think the power from the Showcase is good for center and surround duty but your 803's will really open up with the 2250. Beautiful room by the way. Great gear too. I would never leave the house :-)
