Anti-skating question

I recently installed a new phono cartridge (DynaVector 10x4 MkII on Origin Live modified Rega RB250 on Planar 3 table). At first, I set the anti-skating force so that on a spinning grooveless record surface the tonearm would pretty much stay where it was set down or drift slowly outward. That, I assumed, was a pretty good and direct way to set the level of anti-skating force needed. Then, I put on HiFiNews&RecordReview’s test LP and used the anti-skating tracks – basically, you adjust the anti-skating until you hear no tracking distortion of the test signal in either channel. This procedure gave me a very different setting – one that does not counter (not nearly totally, anyway) the inward skating of the tonearm when set on a grooveless record surface. I would have thought the two methods would have produced more similar results. Any explanation for this? (I’ve stuck with the sonically-based setting for now.)

Interesting. My results were counter-intuitive (or at least counter to my expectations), and it's reassuring to know that others have gotten the same kind of results. Thanks for posting.

This question is for Jayboard: Can you tell me the results of the O.L upgrade. What did they do, I know they replace the tonearm internal wiring. Is this one run all the way to the rca's, did they replace the end of the arm with a weighted stainless end and the same upgraded counter weight? What was the cost? respond to fcone@mediaone.net thanks JP

Hi, Joepetro. Not to put you off, but I don't think you can do better regarding what's involved with the upgrades than the OL site, www.originlive.com. Anyway, the numero uno upgrade is structural, not electrical. OL re-machines and replaces the counterweight and counterweight stub to reduce resonance in the arm. Upgrade of next importance is internal arm rewiring. After that the rest of the wiring. I bought direct from OL new RB250 arm for ~$130 with first and second upgrades at ~$88 and ~$82, respectively. You can probably do better buying in U.S. from Galen Carol Audio, and I think there's another American distributor now. BTW, OL has a pretty good selection of phono cartridges, and if the exchange rate is still good, buying overseas from them amounts to a very good deal. HTH.
