It's highly doubtful the Yamaha, or any avr for that matter, has the right connections to test the Denon. It would have to have an "amp in" or "main in" connection to be able to use the the Denons "pre outs".

Do you have a local audio shop with a 30 day return policy? If so go and buy an amp bring it home and try it then return it.

When using an external amp you connect the speakers to the amp not the avr.
