805 + center + rear

[abba]

Hi I am new to the wounderful world of B&W. I am in the process of putting together a new system and need your advice. I have the oppertunity to purchase an 805 demonstrator for $1500 front speakers, cdm-stn $700 also demonstrator rear speakers and htm7 $750 new center speakers. Also a rotel rsx-1067 a/v receiver.

My question is 2 parts. Will these speakers work together for a good sound and is the price reasonable or should I rethink the whole thing.

Thanks in advance Abba
