I think VTA on-the-fly is overrated. I had that on my Clearaudio Ovation and found I never used it if I wanted to listen to music. When I upgraded to a Clearaudio Innovation I didn't bother getting the arm board that supports fitting the Clearaudio VTALifter2 (i.e. on-the-fly adjustment) I still have.
The thing is lathes that cut lacquers for LPs aren't even consistent enough to make dynamic VTA useful, unless you plan to set it by ear for every record before playing the record (yeah, that's as painful as it sounds).
The Clearaudio Concept supports adjusting VTA statically when changing cartridges. It's a matter of loosening the bolt that locks the tonearm in the armboard.
