Esoteric K-03/Plinius CD-101

Hello fellow audioholics
I am seeking some advice on Esoteric CD players.
I have Dynaudio C4’s with Plinius SA-103, Tautoro and CD-101 with Kimber Hero I/C’s but although I am generally happy with the CD101’s sound I’m considering replacing it for various other reasons.
I’m interested in trying an Esoteric player, potentially the K-03 and was wondering how much of an improvement this player would be compared to the CD-101 with Redbook CD’s as unfortunately I have no way of auditioning.
Can those who have heard both players please comment on what they feel i would gain.

Thanks very much
