My 7.1 capable Onkyo had this feature, and I was wondering if other brands had something similar, in particular the new Yamaha 1400/2400. When listening to 5.1 or Dolby surround sources, the Onkyo could send the surround right sound to the rear surround right speaker and likewise the surround left sound to the rear surround left. I really liked this feature as it opened-up the rear surround field when not using EX/ES source material. I was at a dealer's, and he let me see the 2400's manual (the actual unit wasn't on the floor yet), but the manual was unclear in the implementation of this feature. It also looked like that if the 2400 was powered down, the preference setting for this was lost. Be sure to mention make/model if the receiver has this. Thanks.
