1. for the money, which is the best value in the B&W line - the 700 series or the 600 series? (or the CM line in between)
2. would the 70wpc NAD753 be enough power for the 700 series? my listening area is pretty large but i don't listen to very loud music on a regular basis. just wouldn't want to strain the 753. it's not too late to return and upgrade to the 763. any thoughts?
