Help Choosing Which Sony DVP/BDP

I need a Sony DVD player with 5.1 analog outputs because I own a multichannel analog preamp instead of a processor (and I want to keep things that way if possible).


My current Sony DVP-NS3100ES experiencing a lot of issues, so I'm thinking of a change to some other model on the secondary market. I could get the DVP-NS9100ES, but it's a lot of moolah for a redbook DVD player. I could also get the BDP-S1 or some other blu-ray player for less money, but my TV is only 720p/1080i and not 1080p.


The player has to be Sony because that's the *only* vendor whose players don't choke on all my personal backups. Oh and obviously the player also has to have hdmi output, regardless.


So which player in the Sony DVP or BDP lines has the best 5.1 analog sound? Any thoughts?
