$6 Million Dollar Man?

Actually, you couldn't get an endless slew of "A list" performers in exchange for that money! I think some of the top people get like $100k per hour, if they do such part time gigs at all. At that rate, you'd blow through the $6 mil in a few weeks if you were to pony up ever night! Ouch!
Yeah, that and of course you at least know you'll get their best when you buy or play a recroding. Live, you might be disappointed if they're not motivated or into it that night, off night, bad setup, and so on. Naw, the $6 bills is cheaper...plus you can choose your own agenda, and it's all yours.
Yeah Diva's and moody primadonnas' needn't apply.

Glass tables, gear between sweet spot and speakers, obnoxious track lights and a polished wood floor that resembles a basketball court...can you say defraction?

My first problem in that room - besides all that equipment strewen all around the room - is equipment being in the same room with the sound system. No matter what, you're still getting feedback into the system.
The floor reflection? Yeah, it's not as big of a problem with that style of speaker (especially if it's first order crossovers). With all that reflection/diffusion throughout though, unless there's enough mid/high absorption in that room, it can sound a little bright and thin in weight. The room probably absorbs enough bass overall, given it's size. My experience with a similarly large space -particularly the main sound dubbing stage at USC - is that mid/hi aborption is needed to balance out the sound in a largish space. The floor could, I agree, use a rug thrown down likely. But I'd have to listen to that system in that room, and see more of the acoustics, ideally. Still, from what I see, it looks like a throw rug, at very least, could only help between the speakers and seating, in an "equipment room setup" type of system like this.
The little glass coffee table? Well it looks like it was intentionally kept on the small side, which is good. Better would be a firm aborptive padded top table, if you must have one.
The lights are likely high enough above the seats to not be in the eyes, and will only break up sound on the ceiling a bit, if enough of them. I'd be more concerned here with making sure they didn't rattle, if anything.

Saw it. Did you see the $10 million room with the pool? I don't think it had a sound system.
