Just wondering, because I've never used a receiver with Audyssey, but can it store multiple settings? My Pioneer has 6 memory slots which each can store completely different MCACC configurations. So it could be run once for the first set of speakers, and again using a different memory setting for another.

Pioneer PDP-5020FD, Marantz SR6011
Axiom M5HP, VP160HP, QS8
Sony PS4, surround backs
