With Rega 3 point mounting system for tonearms, the after market VTA adjsting ring gives you relatively quick VTA adjusting if needed. On My P3-24 when I had the RB301 arm on it I was able to shim it with 3- 4mm high small hex nuts, when I mounted my Denon Dl-110 cartridge on it. It took 2-3 minutes and looked just fine. I now have a Jelco SA-370H arm on it and it has an adjustable VTA collar.
