Inner tracks vs outer tracks

Miller: "There should also be changes as the Earth turn's on it's axis and magma shifts affect local gravity". So the amount of anti-skate adjustment would be dependant upon the turntable's placement orientation in regard to the direction the Earth is spinning? 

Dear @almart1 : "  May be due to better system resolution. Which bothers me a little. "

A linear tracking tonearm can't improve per sé the quality recorded sound in those inner LP grooves.

Any one can improve the inner grooves quality sound if: the choosed cartridge/tonearm combination is well matched, if the cartridge has high tracking abilities, with a really good phono stage and with a truly rigth cartridge/tonearm geometry alignment set up through an accurated protractor.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Almart1,
a linear tracking arm like the Kuzma Airline or the Eminent Technology 2 will help to solve your problems.
another approach is the UNIdin curve you get when buying a Smarttractor. This geometrical solution solves your problem much better than any other curves.

Dear @thuchan : After all these years I’m sorry to say it but maybe because you still don’t understand the geometry algnment issue you are really wrong with your statements, especially that alignment option that in reality can’t help on the inner grooves distortions levels as you said.

You can look here about:

https://www.analogplanet.com/content/uni-din-versus-l%C3%B6fgren-b-just-clarify

there the Löfgren A alignment inner null point is at 66mm. against 63.3mm of the other alignment. Please explain how that makes not a true difference but is the solution for the OP?, even Löfgren B makes a good work at 70mm and way superior to " your " touted alignment all over the other parts of the LP surface grooves.


In the other side: how many LPs has the OP with grooves/recorded at the inner 70mm-60mm ?

Do it you a favor and read the last 3 posts in that MF thread linked.

Btw, after you understand the main geometry alignment subjects/characteristics you could easily " design " your own alignment and I mean it. Every one can do it.

So try to learn by your self because your statements means that after over 15 years you are " seated " in the same chair with out growing-up because you are and converted only in a " follower " ! ! but learned almost nothing. Are you satisfied with?

Do not do it through other people and remember that there is no single perfect solution for the cartridge/pivoted tonearm geometry alignment. Always exist trade-offs.

Dear Raul,
the MF article is 6 years old.
Wally tried to determine UNI-DIN in the vinyl-engine calculator and tried to compare it with the stipulation of Loefgren. It is not only far away from reality, I guess Wally did not understand UNI-DIN (same with you?).

Mathematically and under the assumption that the tracking parameters were the same on each LP-side Loefgrens Euclidian Approaching would be correct! As either the one nor the other is correct the bases for the calculation is not right - especially not for Stereo!

UNI-DIN was accomplished on the bases of a Stereo-Microgroove LP. The Stereo track, nor 33 1/3 or 45 rpm existed at the time of Loefgren ´s calculation. The same for Baerwald.

When you want enjoying a LP with all tracks you better move to UNI-DIN, also regarding the last songs on the record.
MIchael Fremer knew why he did not prefer one of the curves at Wally´s miscalculation. Maybe today Michael would see it in a different light?
