Denon DVD 5000. It's discontinued now. You should be able to find it used for $1200 to $1400. It upsamples some CD audio -- read the reviews, has HDCD, is extremely heavy and vibration free, and generates a great artifact picture.
Best DVD Player for around US 2,000
I'm looking for the best DVD Player for around US$ 2K. From my point of view, it got to have Progressive Scan (real progressive, with 3:2 pulldown) and the best black level possible, considering that it will be used with my Sony Plasma Display, which does not have the greatest black level in the market.
