I'm curious about anyones thoughts on this. Specifically, are DVD and/or Universal players put out by a company designed to sound best on that companys products not someone elses. For example is the Denon 1910 DVD player going to sound best when played with a Denon receiver or something like the Harmon Kardon AVR 635 receiver going to sound its best when played with say a Harmon Kardon 31 DVD player? I'm almost tempted to "'rent" both the Denon 1910 player to try with my receiver & the 635 to try with my DVD player to see if they'll sound noticeably better & if I'm totally knocked out,, buy them cheaper online after I returned them to the stores I "rented" them from.
