Harry Weisfeld Was Right All Along

I'll admit that I was skeptical when I heard Harry Weisfeld of VPI say that his JMW tonearm sounded better without any antiskating device a few years ago. All the arguments for antiskating compensation seemed plausible if not undeniable.

But today, I've seen the light. I own a Michell Orbe SE with a Wilson Benesch Act 0.5 arm and a Shelter 501 II cartridge. I dialed everything in, but still had the compunction to fiddle around with something so I removed the funky anti-skate weight from the WB. Not only does the arm behave much better (no annoying, backswing when indexing), but it actually sounds better to my ears. Smoother, more dynamic, less etched/more natural are the changes I hear. I wonder how many other arm/cartridge combinations would benefit from eschewing their anti-skate mechanisms.

While I originally thought that Harry Weisfeld was simply making excuses, in reality, he was probably just being honest. I'm sure the twisty-wire approach he now uses is a good way to implement anti-skating for those who must have it.

I would suggest you read more on audiogon about anti-skate. I agree that uni-pivots are a different case, and it seems that people who own these arms have to look into it differently. Has someone done anti-skate by ear for uni-pivots? Why would anti-skate be necessary for linear tracking arms? Logic(as in HW being an expert on analog, and therefore correct on anti-skate) may or may not lead to correct conclusions. Note also that some cartridge manufacturers recommend a much lower anti-skate than VTF, which may be due to stronger cantilever materials?

To be absolutely correct, it wasn't Harry but Joe Grado (and sure Mitch Cotter was involved somehow) who pointed out the "compromises" involved with setting antiskating on an LP.

Stringreen, I can assure you that TWL knows what he's talking about. (I wonder if Tom still scans these forums from time to time.)

The forces that led to the need for AS are always present. The need to apply AS is not always present, IME.

I haven't used AS on my Triplanar in over a year.

As for uni-pivots and AS. I have a new Durand Talea, which is a uni-pivot for those not familiar with this new arm. I've mounted Lyras, Dynavectors, Transfiguration, ZYX, and Shelter cartridges so far and have yet discover any situation that shows ANY need for anti-skate. YMMV, and all that.

I have always wonder about setting anti-skate. Typically, I ignored instructions and merely put a blank record on a dropped the needle and adjusted accordingly. But for some time I had the Shindo turntable with it updated Ortofon tonearm which never had an anti-skating adjustment.

You have no concerns with anti-skating with linear arms, but they should be perfectly level and move neither way.

I found this thread by searching for anti-skating w/ Wilson-Benesch ACT 0.5 tonearm, and I've had results similar to Plato's. I set up a NOS WB ACT arm on an Oracle Premiere TT and set the A/S per the manual. Initially it seemed to work okay, but after about 100 hour of play the A/S force seemed to increase and the trend of the arm backswing during queing an occasional back skipping I tried to reduce the A/S setting. I could never get the adjustment for ball on string method to change enough no matter how far I set it back towards the arm pivot point. So I finally gave an remove the A/S ball and string.
Any comments on this? Is it feasible that the unipivot arm bearing wearing in defeated the need for the A/S?
