I'm researching now but have found only one solution that fits my own needs. I prefer to have a few options.
TV: 55" diagonal, ~80 lbs
Receiver: 17.13w x 7.28h x 17.36d", 33 lbs.
Center Channel: 20.5w x 7.5h x 13.5d”, 30 lbs.
Additional gear that I'm sure will fit with little problem: Oppo 93, DVR, Mac mini, Apple TV, X-Box 360.
The apparent trouble is that I'm looking for a unit that's about 52" wide. Better still something that can work in a living room corner. I was (naïvely) hoping to keep the cost at or south of $1,000, but it seems $1500-$2200 is more realistic.
Thus far, BDI's Novia 8421 seems about perfect, but I don't like buying the ONLY thing I can find and that's the case at this point. I haven't seen this particular BDI unit in person but saw another model in-store, so that helps me feel better about the quality. I'm uncomfortable spending this kind of money based on Internet images and reviews on merchant sites since physical limitations make potential disassembly, re-boxing and returning very troublesome.
