VPI 2nd Pivot for 3D

Raul,

The link you provided is for a sales pitch of the Mark Levinson/VPI turntable.  Please send the link again.  Thanks.

@billstevenson Raul’s point is to look at 12s in where there is a needle drop with an Ortofon cartridge, the arm swings noticeably which Raul maintains shows the inherent instability in Uni-pivot designs (absent a pseudo second pivot like the one under discussion). Funny thing regarding this video is that the ML turntable is actually a gimbal design, the stupid art director for the video dropped in a shot of some other VPI turntable! This was all discussed earlier in the thread (see entries dated 7/26-7/27)

If folkfreak's post above is accurate, it should have been corrected immediately so as to not deceive in any way, future customers! However, it's easy to find videos of the arm swaying side to side until it becomes steady by way of natural causes, which is the entire argument in a nutshell, isn't it? I experience it every time I lower the arm onto a lp.

@billstevenson, My posts regarding the different clamps/weights involved comparing them alone and with my mats and the differences I found. The mat/s won out with no weights/clamps easliy.

Dear @billstevenson : @folkfreak is rigth. The tonearm in that video is a VPI unipivot one.

@slaw  posted """  it's easy to find videos of the arm swaying side to side until it becomes steady by way of natural causes ..."""

as a fact that instability happens in any unipivot tonearm, is inherent in this kind of tonearm bearing design.

In that video we can see the instability at macroscopic level but that instability coninue all over recorded area at microscopic levels.

As folfreak said all those already were under discussion through this thread.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.

I’m reminded of the Art Dudley video. Anyone watched it? In his wisdom he states that we are all listening to distortions in some form or another. It comes down to which distortions agree more with one’s own perception of their musical truth.

Sorry Raul, while I tend to side with you in this particular discussion, your "...enjoy the MUSIC NOT DISTORTIONS" is a valid pursuit, but not a reasonable ultimate reality.

I think the best compromise to the "2nd pivot" is @robes initial question regarding the Townshend trough. If available, it would not only address the "swaying" without adding a "2nd pivot" thereby changing the whole arm’s reason for being, but positively affect the cartridge resonances. A more perfect option.

@stringreen’s statement earlier that the cartridge’ suspension should take care of the 3D arm sway is I think, asking too much of the cartridge.
