Sony DVP-S7700 DVD Player
This is probably the best DVD player out there
I have owned my Sony DVP-S7700 player for some time and I never had any problem with it.  Therefore, I was amazed that some people actually had a problem with this player as posted in some of the other reviews.  I, for one, found the sound quality to be excellent.  Incidentally, of all the professional reviews I read on the S7700, never once did I see a review mention that the sound quality of this unit was only fair.  Articles I have read have also compared this player to a top-of-the-line cd player.  And I agree with them.  After installing my player, I can honestly say my cds sounded better.  This has me convinced that not all cd players sound the same.  My only thought for people who are having sound problems is perhaps they should have a home theater technician look into their setup.  Maybe all that is needed is a small adjustment and then they will know what the rest of us are talking about when we marvel about how great a DVD player this is.  In case you are wondering, I do not work for Sony; I am just a very, very satisfied Sony customer.
