I bought the NAD C521i a few months ago. As far as analog output, it is like night and day compared to my Kenwood cheapo. The D/A converter in the Kenwood must be pure junk. My only complaint with the C521i is the display is difficult to see if the unit is placed too high or low from a straight ahead viewing position. It is a no nonsense type of player with basic features. Let me know if you have more specific questions about it.
