I see there's a little questioning about the advantages of the BeoSystem 3. They're the same as they've always been, but the most surprising is that no one is perceiving the blatant PQ difference between the BV7 & BV10!
One interesting thing about my shop versus the others I've seen is that I play a single source on all the TVs at the same time. Gives the shop a nice calm look. Anyways, you can easily look at a single wall and see a BV7-40, BV7-55, and BV10-40. The PQ on the BV10-40 & 46 is no where near what it is on the BV7-40 & 55. This is partially due to the edge-lit v. back-lit difference and partially due to the inclusion of the full BeoSystem 3. Colors on the BV10 are not as accurate, blacks are no-where near as deep or nuanced, and motion is significantly choppier. Still better than its Samsung brothers & sisters, but can't hold a candle to the BV7-55. Of course if you're watching two different things it's harder to see that difference.
Back to the BeoSystem 3:
7.2 v. 5.1
Dual viewing mode with two separate sound stages
More source inputs
More PQ horsepower (this is the most valuable in my opinion)
Dual link master
AST
Mux out
All that being said, I've repeatedly argued for a scaled down version like the one built into the BV10 or BV8-40 to be sold as a standalone product for 3rd party screens. So I'm not saying this to somehow counter anyone who's commented on its usefulness. Many people don't need the home cinema related advantages it offers.
