The Esoteric K-01X has been performing flawlessly since I purchased it, and got the TRAY error to fix itself by pushing the ON button and the OPEN button at the same time, and holding it for about ten seconds, which allowed the system to do some sort of self-check, and fix itself.
I was just reading back over my posts here, and I don't presently have the problem with SACD vs CD that I apparently commented about; however, I have switched out some gear since then. In fact, I'm mostly listening to vinyl, but this Esoteric CD/SACD player is a main component which got me more interested in upgrading my sound system overall.
Hope you're doing well. Thanks.
