You could also buy 3 HRS nimbus dampers/couplers and place them on top of the Bryston and place the Oppo directly on top of the nimbus couplers/dampers. the damping/control they provide to my Oppo is remarkable...particularly with an HRS damping plate on top of the Oppo over the cd drive area itself. the nimbus couplers/dampers come in two heights...about 3/4 of an inch and probably 1.5-2 inches.
good luck!
