My primary concern is optimum quality when listening to cd's.
I spent some time at Magnolia today listening to several receivers.

Onkyo - 770W 7.2-Ch. Model: TX-NR709

Marantz - 700W 7.1-Ch. Model: SR5006

Yamaha - AVENTAGE 770-Watt / 7.2 Channel / RX-A1010BL

Onkyo - 945W 7.2-Ch. Model: TX-NR809

I listened using the B&W 685's which are most similar to what I own.
The Marantz was in "safe mode" whatever that is so I didnt get to hear that one. The Onkyo 709 seemed to resonate with me but I know they run hot and have had firmware issues. The 809 is more than I want to spend. I need to go back and listen to the Marantz tomorrow.
