I looked at this system (and this brand in general)... First off, this system is not worth $5,000 in any way, shape, or fashion. At their said "MSRP" they even make Bose look like a bargain. LOL
You should research this product from different sellers and different websites and see whether things on this product are consistent or not. Also, look to see if this product actually exists with some real pictures rather than computer generated images.
Bottom line, as the old saying goes, "If it looks too good to be true...it probably is."
If you're looking for a super deal on a surround sound system, I recommend entering the auction realm and search for 1¢ to $1 auctions with no reserve, and every once in awhile a system will sell for pennies on the dollar -most of the times used, but sometimes a new system is up on the auction block. eBay is a good place to start.
