I have friend with a DV50 and it is a wonderful CD player. I have the C5xe and recently had the MP upgrade done by Ayre. In comparison between the two machines I would say that the Ayre delivers a much more natural toneality. There seems to be an equal amount of information coming from both machines but the Ayre's natural tone delivers in a less analytical but detailed sound stage. These are of course my opinions, which seem to be shared by the owner of the DV50. YMMV.
