I can't offer any assistance but will follow the thread as I have pondered the same question after owning the X-03SE for a number of years now and have wondered what, if anything, the K-03 would do in my system. We seem to have similar tastes
so whatever you find out through auditioning would be much appreciated!
Esoteric X-03se vs K-03
I've enjoyed the X-03se for some years now in our 2-channel system. I'm curious however, as I've yet to see any reviews that directly compare the old to the new - X-03se to the K-03. I've read the published reviews, and realize the K-03 has improved accessibility (USB, etc), setting adjustments,et al, but are we to assume that, because it is the upgraded version, it improves upon the X-03se sound/presentation in every way? Anyone been able to do an A/B?
