For VPI Unipivot Owners, do you use antiskating?

Dear Adeep,
You should try AS. It seems an obvious thing to say but before tinkering with AS try to get the platter as 100% level as possible in all axes.
With some suspended tables this is easier said than done. I've seen suspended tables visibly tilt/oscillate under the influence of belt pull (either due to poor weight distribution/balance of the platter and its add-ons or forces acting on the sprung assembly or poor levelling of the plinth or all 3).
An unsuspended mass damped T/T is much easier in this respect.

Eyeballing cantilevers is not my preference, although I usually do a cursory check on the attitude of the cartridge during queuing at the run-in groove. Old advice was that the cantilever should remain stationary and wait to be picked up or it should drift slightly outwards? (Either on the innermost blank area or the outermost - they used to cite 5mm/sec outward drift). This is no longer the case as that would be considered to be over-compensation.
Listening is easily the best way to confirm this. My tonearm doesn't lend itself to active adjustment during play so I do it in stages.

Important to remember that strong bass signals tend to be encoded equally in both L-R channels. If AS is wrong then the cart will tend to ride up the slope of either channel. This is tantamount to a sort of channel-specific incorrect VTF, even if it is not blatantly mistracking.
You will hear L-R frequency balance changes as you alter AS.
To illustrate this to non-believers in the past I've actually done digital needledrops showing the effect of different settings.
Hope this helps.

Moonglum...surely the sound will change with an increase or decrease of a/s....you're dragging the stylus closer/farther to the magnet or coil. No one can control the a/s that's needed or preferred because the force is constantly changing. Why don't you listen to your cartridge without a/s and let it breathe. If you don't like it, put your a/s in play again.

In my experience (as described earlier), all of it involving MM and MI cartridges, as I had mentioned a change in anti-skating force of about 15% from the value arrived at per the procedure I described will result in EASILY perceivable deflection of the cantilever from its normally straight-ahead position. Yet at the same time, as I said earlier, once I have adjusted anti-skating force per that procedure there is NO perceivable deflection at ANY point on the record (apart from deflections that may be caused by large groove modulations, of course).

That would seem to say something about the DEGREE to which skating force varies during the course of the record.

Dear Stringreen,
You must have missed this bit :

"If AS is wrong then the cart will tend to ride up the slope of either channel. This is tantamount to a sort of channel-specific incorrect VTF, even if it is not blatantly mistracking.
You will hear L-R frequency balance changes as you alter AS."

It is generally accepted that neutral A/S is a compromise to the individual's ears but not having any at all could be as catastrophically bad for the diamond as having too much. (Not too sure about the effect on the lateral suspension either, to be honest).
Asymmetric wear is an option that many folk don't want to risk when they've shelled out real $$$$ and sadly this wear pattern is documented by Studies and confirmed by cartridge builders. So it is an inescapable fact :(

I appreciate that you feel you've found something good and that you want everyone else to share it but the practicalities are that there is danger of damaging both diamond and media - a risk which you have accepted.
Kind regards,

... the practicalities are that there is danger of damaging both diamond and media - a risk which you have accepted.

Exactly so, per point #2 in my 3/9/15 post above.

Enthusiasm for good sonics should not cause anyone to ignore the risks, which are real. If Moonglum chooses not to accept those risks for possible sonic benefits, that choice is valid.
