It's the Sony XA5400ES the best CDP under 4k

I wonder the same thing about the Sony 5400ES player I own as to what it would take to better the Sony. I wish I could just compare different players in my system. I know the Sony keeps up with my improving and maturing sytem. I do not feel like it is the week link in my stereo system. I may be crazy but I am currently using an Elrod power cord and a pair of Purist Dominus Praesto interconnects. This is the best sound I have heard from the Sony. The bass is much fuller and the midrange is very nice. The treble seems now to float in the air. I am liking what I hear very much.
