VPI 2nd Pivot for 3D

Dear @billstevenson :  """  We do the best we can. And you know what? Don't despair, our efforts are not in vain.... """"

in those words you resume what I try to explain through my last post to you.

Now, the cartridge/tonearm geometry alignment it does not cares on all or any of the imperfect characteristics analog/LP has. Always we have to try that that set up been do it with high accuracy.


"""  a vinyl record very often sounds better than the digital equivalent for all it's claimed perfection.   ... """

Today that statement is so controversial for say the least. Today digital technology advanced " ligth years "  in the last 10 years and I think that today is way superior ( everything the same ) to analog/LP experience.
Digital is still growing up almost single day. I enjoy both formats but I know that digital outperforms analog. We can " close " the sun with one " finger ".
Analog is at's limits when digital still growing up and this characteristic is a welcomed for any music lover and audiophile.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Dear @geoffkait  : """  That's why the geometry should (ideally) be changed for almost every record. """

Can you share with us a wider explanation about?, is interesting to know why we need to change the geometry at each record.

Due to the variation in thickness of the LP the geometry of the cartridge/tonearm changes significantly, enough to produce 1/10 degree change in geometry in some cases. Don’t they have on-the-fly geometry adjustment gizmos?

Sloppy language @geoffkait "geometry" typically refers to the alignment of the stylus relative to the preferred arc and (absent gross off center issues should not vary disc to disc ('tho the truly anal might switch chosen geometries depending on the disc they are playing and where they want to put the maximum distortion 😉))

what you describe would affect the VTF/SRA/VTA relationship which while an important part of cartridge setup is not usually thought of as geometry. Plus it's easily addressed via adjustment of whatever VTA mechanism you're using

Ah, so you're saying vertical tracking angle is not geometry. Interesting.
