Definitely check out Decware's modified Sony DVP-685. There are no opamps or electrolytics in the signal path, no negative feedback and a class A SET tube output with it's own power supply. Price is under $700. Lots of info on the site describing mods and a couple of reviews on their forum, including mine. It's worth a look, I love mine and I don't believe there is another tubed SACD/cd/dvd/mp3 player on the market at that price.
