So, it's broadly the same as the box reviewed in September but bigger. The sound's not outstandingly good - but if you're able to afford 2100 on a display unit, you're more than likely to have a dedicated system for sound anyway. The main difference is the inclusion of 3D tech. but that's not widely supported now, nor will it be for the next three or four years (again, if you're prepared to shell out 2k for this feature now, you'll be back for a 3D 2.0 setup in three years' time regardless).
So, who's this device aimed at? If they're AV buffs, they'll want 'box that's pure 'V', leaving all the 'A' to other kit. If the intended market is the general buying public then it's overpriced. Perhaps the target buyer is anyone with a very high disposable income? If so, these are (generally) not that interested in knowing if this is technically any good - so I'd question if Reg. is the right place for a review: 'Surrey's Banker Belt Digest' would be a better bet....
Just saying. Mind you, it does look nice. For the money, I'd expect to be able to change the bezel to blend it better with my decor, especially if it has the Ambipure or whatever it's called that lights up the walls ;-)
