Uni-Protractor Set tonearm alignment

Raul,
Having read the papers, in my understanding of tonearm physics/math, there is no reason one cannot 'adjust' EL by 0.5mm and then come up with a new set of parameters derived from your preferred alignment (as long as the headshell is flexible enough (in terms of mounting holes)). It will no longer be 'official' but there should be room to play if one wants. Perhaps I have not properly understood. I will noodle it around a bit.

As to the other part, your idea of speculation and mine are obviously different. I think it speculative to assume that a change in the physics will have zero effect until a white paper tells me so. I have certainly not comcluded anything, but I am inclined to be open-minded, even without the white paper.

Dear T_bone: Of course that we always can change the EL and I posted we can.

On the other subject and due that's so simple through the different VE calculators ( thank you VE! ) when you or any owner of the DT protractor have it on hand you can take the parameters from cartridge/tonearm ( no big deal. ) where the protractor was used for the set up and use that " numbers/data " on the VE calculators and confirm if you have lower distortions over the LP recorded area against the normal calculations or against the manufacturer numbers.

In this subject we really don't have to argue/ask anything other that : after calculations shows lower distortions numbers/values or not?, easy!!!! , here the subjectivity does not count what you, me or any other person could think does not matters at all ( well always an opinion matters but you know what I mean. ) the easy VE calculations tell us the real distortions levels against other set ups.

Btw, when I talked of white papers it's only those simple calculations and that's all.

Regards and enjoy the music,

Dear friends: I think that is important to remember that what I'm talking over the thread and IMHO over those white papers outside is to align the cartridge stylus/cantilever where the pivoted tonearm is only a tool and a " must " for do it. From the tonearm we need to know only the effective length and that's all.

The star is the cartridge ( is the source if we don't take in count the LP it self. ) but it needs the tonearm to hold it.

Dear friends: IMHO any manufacturer protractor with multiple set up alternatives, like the DT protractor, should/could gives his customers the chart with the different distortions level with each set up geometry/template for the set up.

IMHO we customers need to know at least which is the distoprtion level to decide which one to use, I think there is no reason for a protractor of this type does not comes with this main and critical customer information.

Dt, what do you think? could be?, thank you in advance.

Attitudes like the VPI manufacturer that undisclose the tonearm set up parameters IMHO is wrong because we are the customers and we have the right to know about, this kind of information is not a " subject " that you can attain a patent and even if yes: which the problem? why manufacturers put on sale audio items for " blind/unable to speak " people that things are we are not " blind " and certainly we can speak to ask.

Anyway, only a thought.

Regards and enjoy the music,

Of course that to make comparisons the effective length must be the same because if we increment ( any increment, it does not matters how tiny. ) the EL distortions figures goes lower, the same happen when we increment the most inner groove distance on Löfgren A/B calculations.
