Your price range is most likely the reason you are not receiving information.
There are some good sonys out there, but by far the best, although above your range, is the Oppo 93. This player is used as the base by many, many ultra high end companies and players. Lex, Theta, etc all use Oppo as their base, I cannot remember all of them, but do a search on here or google and the list is long.
for 500 you get a player that does more and is more accurate than most players that cost an order of magnitude more.
