The reason I put the A2x ahead is lossless sound will be transcoded to DTS via optical outputs.
IMO, the A20 is better than the A2 only because of the upscaling. 1080p isn't done perfectly on any of these, and with a good 1080p set, there's no difference between 1080i/p.
IMO, a fair value for the A35? $150-250. I know the XA2s still go for a decent amount, but the A35 isn't as highly regarded in the DVD upscaling.
yea, the higher-end players are pretty rare. HD-DVD was always selling on price, and having a $799 player didn't look worth it next to a $299 (or less) player. I bought one, but I know compared to the general public that bought HD-DVD I'm a minority. Here, not so much!
