I'll start with some background - I have a Marantz SR5300 AV receiver/amplifier with which I have been using a DVD player connected via a digital coaxial to play CDs with pleasant results. However I have recently changed my DVD player from a Wharfedale which sounded really nice to a pioneer which sounded less nice. I now have a few questions which it would be really helpful is someone could answer 1. Why do these two DVD players sound different when connected through the digital coaxial cable (and therefore presumably using the amplfiers DACs)? 2. Due to the difference in sound quality I was considering buying a separate CD player (something like an NAD 521BEE or a Cambridge Azur 640C is the budget will stretch). However I have read that any input you feed into an AV amplifier goes through the amplifiers DACs - so would this negate the point of buying an expensive CD player? Or would it sound better if conncted through the analogue inputs? 3. Would I be better off just saving up and buying a separate CD player and stereo amp to avoid these problems? Thanks in advance for any replies / information that you can give me - I have managed to get myself really confused over the last couple of days!!
