Esoteric if you like your music mechanical and lifeless. I have always found the Esoteric players mechanically fantastic but musically okay at best. They usually excel at bass and treble detail.
Use the Saturn with better isolation feet and then decide. The standard feet kill the player and make it sound soft.
I have found a properly set up Saturn to be a fantastic player and it is less expensive to boot. Tremendous sound stage, great detail, and a lush smooth mid- range.
Your best bet is finding a dealer who has both or can lend you one at a time and then decide for yourself.
