I realize I'm going to sound like you know who but, with the Technics 1200, VTA adjustment is simple and can be done on the fly, albeit very carefully. I usually lift the tonearm and change VTA settings and then drop it to listen for a bit, then lock it off when I'm satisfied.
On my SME arm, VTA adjustment is as medieval as the Rega.
To be frank about it, I've never heard the dramatic differences that are claimed by guys over on the Asylum.
