I recently ungraded my dvd player from a philips 701 (2 year old model) to a new 724at. I even bought a new fancy digital coax cable with it (almost half the cost of the dvd player!). I can't say the sound improved at all. even switching between a cheaper coax cable and a toslink cable had no effect on the sound at all. since they are used as transports the sound (movie) should be the same right since its all digital. My question is how much money do you have to spend for a dvd player for someone with a lo/mid-fi system to notice improvments in sound quality(DD/DTS sound, not CD sound) using the players as transports. Tell me any experiances you might have had when upgrading dvd players. did movie sound actualy improve? I might return the player but if i have to buy something that cost over 300 dollars more than i don't think it would be worth it for just a small improvement. My reciver is a marantz sr6200 speakers are new qx dahlquist thanks in advance for any help.
