Hi all I am currently using pre-outs on a Yamaha RX-V667 into a Cambridge azur 650A for the front L and R channels. I have acoustic energy radiance 2 floorstanders, with the radiance sub and centre speaker and radiance 1 bookshelves as surrounds. I need another receiver for a second room and am contemplating upgrading the 667 and putting that in the other room. If I got, for example, the Onkyo TX-NR709, would it still make sense to drive the front speakers via the 650A? presumably at some stage this doesn't make sense. Any help (or other suggestions) appreciated!
