I want to know whether the dual pivot should be adjusted touching the plate or not while the stylus is in the groove.

Thanks in advance.

First, you never make an adjustment to the dual pivot while the stylus is in the groove. Too high of chance of damaging your stylus. All dual pivot adjustments should be made with the arm secured in its rest. When the stylus is in the groove i.e playing a record, the dual pivot should be contacting the skate plate at all times.

Brf, Just read this thread and was wondering what your impressions of the Dual Pivot Kit are? Thanks.

IMHO, a must have...better performance and better sonics. If I were VPI, I would make this a standard offering and not an option for all future uni-pivots

I just installed the Dual Pivot kit on my Classic 3 today. Very nice addition so far. I really like the stability when the tonearm is rested on the LP. Sometimes my needle used to 'jump' into the first grooves (unless using the outer ring). Now it is totally steady. I also like how this is used to set azimuth. Everything sounding great also. I recommend this upgrade.

This was pretty easy to install. I've played with the set screw a little more to get azimuth correct than anything else.

Bass is a little clearer and transient detail may be slightly smeared as others have reported. I'm still trying to get used to the lack of tonearm jitter after years of VPI unipivots. Cuing up the cartridge to verify alignment using my Mint/Best Protractor was a joy compared to having to wait 30 seconds for the tonearm to stop moving before dropping the needle.

Interesting observation. In my setup, using the dual pivot has increased transient detail, especially in the leading edge of the attack. As to a possible explanation, try backing off some of the pressure on the dual pivot because IME, too much pressure on the dual pivot causes a smearing of inner detail.

What is the best way to do this? Would this also require turning the Dual Pivot height screw? Thanks.

To decrease the pressure on the dual-pivot pin, turn either of the lateral adjustment weights or both to shift the center of mass to the outside of the tone arm. You do not need to adjust the height of the adjustment screw as that would change your azimuth. Once you have the azimuth where you like, do not change it.

Could the same be achieved by adjusting via the counterweight and not the lateral adjustment weights?

Yes, but you're likely to affect tracking force while doing so.
