First, the "bi-amp" on the 606 uses the internal amp for the rear channels. Complete waste of time, but do what you want. It won't hurt (and it won't help).

Second, I decided to go with the M60's over the 80's due to my Onkyo 705's aversion to 4 ohm speakers. The 606 is the same.

Finally, I often listen to music with just my mains (no sub) using the "Pure Audio" mode. They sound terrific.
