Hi Ed,
Yes, you just remove the ball and thread. I left the rubber o-rings on the post because I figured it might damp any tendency for the metal post to ring. I was surprised that removing the antiskate didn't seem to affect the tracking force or the azimuth, but it didn't. So just unstring that thing and tell me what you hear (or don't hear)...
Quincy, I'm not sure how the antiskating mechanism is set up on the SME V. I don't know whether it can be defeated simply, or not. You may not want to mess with it. However, I doubt that it would change or disturb your other settings to do so. My theory is that the effects of antiskating are more pronounced with unipivot arms, for whatever reason. I don't know how much the SME- or Rega-type arms would benefit, if at all. Still, if you find that it's easy to do, you could try it. Also, "5 points of volume" difference seems excessive; I wonder what's up with that. Did you change other things at the same time you were setting up the new turntable??
