I have a 12" 3P on order. From what I understand the only thing affected by azimuth adjustment on this arm, albeit slightly, is VTA. Now I can tell you in my experience adjusting VTA is no big deal. I'll be happy to post my impressions when I have this finally set up but as of now I'm not too concerned. The Talea is another arm with azimuth on the fly, also not at the headshell, and I haven't heard much debate on that so far. Mountain from a molehill? I'll find out soon enough but I'm not too worried. The other thing to consider here is the bearing on the 3P which is different from the other Reeds and should be a significant advancement.
