Am looking this b&w to go with the 685's and a nad 744 amp.

Good choice??

See it at 365USD here in Manila on holidays; fairly cheap, and the 685's are 20pc cheaper than what i paid for them too - any chance fakes? What to look for?

My question is - how will a centre speaker improve sound - mostly music??

and ... could these things ger cheaper in the coming months??

Thx.
