Listened to this today, I had never run my system in 7 channel mode. I spent the whole day yesterday setting the system up from scratch. My new room is set up on the long wall, (27 ft.) with the new 7 channel setup, Room depth is now 22 ft. in this setup. All 7 speakers are now 11 ft. from the center of couch (there is no real sweet spot) so I used this point as one. This is a great multichannel mix, My wife even came in and listened (she never does this) and was blown away. Also listened to Beck and Frankie goes to Hollywood multichannel sacd's, these are a "10" on the scale. Well, gotta go cut the grass.
