People are starting to buy newer receivers with HDMI connections, and they are discarding their "old" receivers. In the last couple of weeks, I have purchased several Dolby Digital 5.1 or 6.1 receivers for about 10% of their MSRP when new. I now have the following receivers:

JVC RX-884
JVC RX-7020
Yamaha HTR-5730
Sony STR-DE597
Sony STR-DE885

I have never owned a Sony receiver before, and picked up those two in the past week. The 597 is newer than the 885, but the 885 is higher end, I think.

Any thought on these receivers? In particular, which is the better Sony for home theater?
