I own both preamps now and I feel that the LTA MicroZOTL preamp with the most recent "plus" mods is superior to the Coda FET 07x preamp by a pretty good margin. The one advantage is the Coda has balanced in and out. Not to take away from how good the 07x is but my setup and my opinion.
A local dealer has thrown another wrench into the works by loaning me a Backert Labs Rhythm 1.3 to try out. Shootout time.
