I want to get a dedicated CD (or a DVD player with superb CD playback), but I am not sure how far I have to go to make sure I buy something that outpaces the DACs in my AVR. Just got the HK 525. Have an old (early 1990s) Sony carousel, 18 bit with optical jack. And I have a basic Sony NS-315 DVD player whose sound quality is no better than the older CD player. It's connected via digital coax. Since both are connected via digital connections, I assume they are passing the music along to the HK, which uses its DACs for final conversion to analog. The HK has a Crystal 192kHz/24 bit DAC. I was thinking of getting the Nad c541i or something similar from Cambridge Audio, Rotel, Arcam, etc. The Nad has a Burr Brown Sigma Delta 24 bit DAC. Would the Nad significantly improve my CD sound? I assume that, if I use a optical or dig coax connection, the HK Dac will have last say in the analog conversion. And if I use a composite connection too, the Burr-Brown DAC in the NAD could handle final conversion to analog if I so chose. Or am I wrong about this? If so, should I just stick with what I have?
