I'm actually not sure, and I won't go digging around to find out, the OP should have told us, in a slightly more detailed initial posting. But he has not been back on the forum since starting this thread.
Hi Darryl, I've had a quick look but to be honest, you really need to look for yourself at the specifications of both amps and decide what you need. Personally, I would not want an av amp more than a few years old, but it depends on the price, age, and condition of the vsx 920.
