OK, I just got a ticket. Personnally, I don't know what I would do with the amp, since my current receiver is only 2 channel.

Wait a second...I see an opportunity. It would be a great thing to push the issue with the wife for an immediate upgrade...
"Look honey, this amp is designed for 5 channels - if we don't fill them all up, it may wreck the expensive amp. Our old Denon is only 2 channels. I think we should go out today and pick up a new one"

yup, that would work ;^) maybe???
