My old Sony DVP-CX850D changer died. I used it for all my cds and a handful of music dvds. It was connected via an optical connection to my Denon AVR 1082. Was very pleased with the sound, worked well for many years. When the changer died a couple of months ago I swapped in an inherited Sony CDP-CX355 CD changer for the cds and a Sony DVP-NS300 player. Cds sound fine, but I swear the DVP-NS300 does not sound as good as that old DVP-CX850D. Is this even possible condsidering the new player is connected with the same optical cable that used to go to the old DVD changer? I seem to remember the changer having a more extensive setup menu than the new player, but I can't check that to verify. I am asking, as I am looking for to a way to stream music from Spotify to my old system. The cheaper methods I have tried using some relatively cheap Parts Express devices sound noticeably flat, so I am exploring options of a blu ray player with streaming capabilities, network streamer, or simply picking up a newer used network capable AV receiver. Just beginning to wade into these options and feel like such a beginner! Thanks for any advice in advance.
