  Если ты всерьез заинтересовался VPI, то насчет антискейтинга могу тебя успокоить - он там есть и его вполне хватает.

А вот что разработчик пишет на эту тему. Слушаю уже неделю - и полностью с ним согласен :

ANTI-SKATING:
• One of the least understood forces acting on a tonearm is anti-skating. Skating
force is created by friction between the stylus and the record creating a force vector
in a direction towards the center of the record. Putting a stylus down on a flat
grooveless record will cause the arm to shoot in toward the center of the record. For
years arm manufacturers have been trying to compensate for this force knowing full
well that it is impossible. The force is constantly changing as the music and the
velocity changes.
• A pivoted arm without an offset head would not be subject to skating force.
However, it will also have no correction for tracking error and the resulting distortion
is unacceptable. As soon as the arm's head is offset to lower tracing distortion,
skating force arises. Greater offsets result in greater skating force.
• After very careful listening tests we have determined that every tonearm we tried
sounded better with their mechanical anti-skating disabled and the tracking
force very slightly increased. All mechanical anti-skate devices add a negative
sound to the music because they are made of parts that can vibrate. We solve the
problem in a unique way:
• As mentioned earlier, the arm wire applies the anti-skating force. The degree of
force applied can be adjusted as explained below.
• To increase or decrease the amount of anti-skating force applied, simply unplug the
Lemo connector and twist it in the direction you want the force applied.
• For example, to increase anti-skating force give the connector a counterclockwise
twist. Likewise, to decrease the force, give the connector a clockwise twist.
Remember, the Lemo connector can only be "adjusted" in increments of whole
turns. If it is not, its key will not line up with the groove in the receptacle.

• We could go on discussing the pros and cons of how much anti-skate is correct, but
the sonic answer is very simple. Adjust the wire as mentioned above until the
tonearm drifts outward when set to neutral balance. When you push the neutral
balance floating tonearm towards the center of the record, it should push back out
towards the rim of the record. Very little force is needed to do this, and the wire acts
like a spring to supply this force.
• This is all you need for anti-skating.
