Esoteric E-02 or SimAudio 810LP

Hey everyone
I am looking to upgrade my phono stage and both of these get stellar reviews.  Has anyone compared them to each other?
Thank you.  I know they are both very good, and I know I could be happy with either.  I own products from both companies in my system.  At this level, some of us only make so many upgrades, so a sonic comparison is what I was hoping to find.

Well, just for the sake of wrapping this discussion up, I bought the Esoteric E-02.  Dynamics, resolution, extension ..... it gave me all of those.  I expect to hold on to this phono stage for at least a decade.  So, I am very very happy with it.
