I've had one of these on order now for what seems like an age from Unbeatable. One question/concern that I have about it is I need the ability to run a seperate set of speakers (in the kitchen). Does anyone know if it has A/B switching? I know it is advertised as having multi room/multi source capability and in a 7.1 receiver you'ld just dedicate 2 of the amplifiers to the second speaker set. However the Marantz "only" has 6 channels - presumably this means you can only run a mono setup? This can't be right surely?
