VPI 2nd Pivot for 3D

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.

In conclusion?... Is this yet another of VPI' finding a way to make a product that at the time, was (well thought out) and later developed an accessory to make that product better? Probably. But we've been through this before, time and time again. And yet we still fall in line to buy, time and time again. At once it's an on-board motor, then an out-board motor, then a tri-pulley, then a rim drive, then a 300rpm motor then a 600 rpm motor then a mag-drive, the a direct drive.  In the end, we're all trying to figure it all out while they are reaping the rewards, time & time again. If you are like me, It's hard to figure out exactly what part I have from which vintage VPI TT? I think looking at their homepage, even they are wrong on the product dates! Shew!..I'm really tired.

So true, slaw. While having made a number of turntables worth owning (though not tonearms---unipivots suck!), VPI has little credibility in terms of a design point-of-view or philosophy. Or, I guess Harry can claim, it has "evolved" ;-).

Slaw - isn't the goal of a company to make a product better, and bring in additional capital for that effort?  Honda is a better product now than it was in 1960, as is Apple,  Boeing, et al.  People vote as to the success/failure of the innovations with their checkbook....the American way.
