Stay away from the 606. I just returned it today. Buzz/hum issue with any unit pushing a hi-def signal through HDMI. It wasn't a ground loop either. I tried everything and could only lessen the buzz.
Anyway, here's some suggestions. All of them have 3 HDMI inputs which you'll need 3 for the listed components, HDMI is repeating (audio and video passthrough), and can play the hi-def codecs (DD True HD/DTS HD)...
Sony STRDG820 $300
HK AVR 254 $379
Pioneer 1018 $434
Denon 1909 $600
All of the prices are from Amazon. You may be able to purchase elsewhere for less expensive, or used.
