KenC:

I've been playing both DVDs & Blu Rays from my BDP-S590 on my new Sony KDL55HX850. Absolutely stunning PQ & audio performance. Upscaling 'The Wild, Wild West' DVD produced visuals that were indistinguishable from BD to my eye.

Haven't tried 3D though - not much in to it.

If they are still available, the S590 is a great buy.
