I'm building a home theater system around Martin Logan Aerius i mains. Is it necessary that I use electrostat for the center and surrounds? or are there other possibilities using conventional speaker setup?
I need 4 surrounds, 1 center, and 1 subwoofer to complete 7.1 setup.
I will use Denon AVR-2802 receiver for the center and two side surrounds and Rotel RB-956AX for the mains (bi-amped) and 2 back surrounds. the second question is, would I get better results with Denon AVR-2802/Rotel 956AX combo or am I better off getting just the Denon AVR-3802? FYI, Denon AVR-2802 comes with 6x90 wpc, Rotel 956AX 6x40wpc (mains are biamped, so 80wpc), AVR-3802 comes with 7x110wpc.

Thanks for your help.
