I have a question though: what are you doing with that Adcom in the rack if you have powered speakers?
I found a use for the Adcom. I'll put it to use as the amp for two rear-surround speakers. I just happen to have a pair of passive speakers that will fit on top of the rear cabinets. Thats no easy trick because the ceiling slopes toward the center of the room. The JBL's have a curved back which will allow them to sit on top of the cabinets and point down toward the listening position.
I know that they probably wont be a perfect match for the Mackie HR824s in the other five positions. I have these laying around so I'll give them a shot. If I hate them than I'll look into other solutions.
