Ayon vs. Esoteric

Has anyone compared the Ayon cd 5s with the Esoteric K-03?
I have the Ayon 2s and am considering an upgrade. I will buy used. Thank you fo your comments.
If you like the Ayon sound signature, you may not like the Esoteric's.

If you are using a tube preamp (or power amp), the Esoteric may be a good match. It's more neutral. And of course the Esoteric plays SACD

But there's something magical about the Ayon's tube lushness. CDs sound "right".

FWIW, I am using the Ayon CD5S as a tube preamp now while the Playback Designs MPS5 SACD is the source.
