Influence of stylus shapes on distortion

Dear Axel: You point out one of the distortion sources: alignment set-up, and we have to add VTF-matching tonearm/cartridge resonance frequency range-AS-load impedance-and the like.

A stylus shape between its shape design has no self distortion other than the one generate for the tracking it self. What generate distortions are poor alignment, poor recordings, poor matching, poor cartridge design/suspension, poor, poor, poor, etc, etc.

A well cartridge design ( either stylus shape ) with the whole correct set-up makes no other distortion that the " natural " one of its work.
Of course that different stylus shape ( everything the same ) give us different information range level.
Of course too that the distortions generate for different stylus shape are different but the important subject is what we can hear about those distortion differences.

I have some same cartridges with in the same model different stylus shape: spherical-elipthical and eliptical-fine line.
In the last case the cartridge sound with the elipthical stylus seems to me a little more relaxed than with the fine-line and I almost can't heard/hear more information through the fine-line.

The distortion subject on stylus different shape that we can hear is very dificult to be precise and absolute on it from the point of view ( like I say ) of what we hear and depends on the whole cartridge design and excecution of that design.

A ML-Fine Line stylus design can give us more information but its whole set-up it is more " delicate " and if it not right on target we can have higher distortions than in a elipthical one. So it is not easy to be " absolute " on the subject.
There are differents ML-Fine Line shapes as different Elipthical ones ( on dimensions shape. ) .

Then we have to be very experienced to say " that is a stylus shape distortion " and " that is part of the recording " even to know when a " sound " is higher or lower in distortion, this is very dificult to discern and only if you are at a very high position on that learning curve you can discern it and obviously with the right audio system: a very low overall distortion system.

Of course that everything the same it can be measure that " natural " each one stylus shapé distortions.

Dear Axel: That was an answer from a " music lover ", I think that the cartridge designers can give us a more precise answer. Maybe JC could help us.

Dear Axel: Here I give you some info about:
http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1235522919&openflup&54&4#54

was not an in deep sessions and maybe at my place the precise/exactly tonearm/cartridge set-up was not right on target but anyways give us a " clear idea about.

I try " hard " with the Ortofon MC 7500 ( same stylus shape that the Windfeld and very close cartridge characteristics.) and is a very sensitive to VTA/SRA changes, it likes to run almost flat/parallel to the record for you can achieve its top quality performance.
It runs good on the SME IV but works better in other of my tonearms. Now, we can take in count those differences on cartridge quality performance only if we have on hand other tonearms to make a comparison, its the only way to understand its true performance.

Sometimes I or some one else say " that tonearm is not a good match with that cartridge " or at the inverse and this kind of stateent not necessary means that that cartridge will perform bad NO.

Usualy a top cartridge performs good in almost any " decent " tonearm and for many of us that " performs good " is enough to enjoy it.
In the other side there are other people that are looking not only for a good cartridge performance but for its best on that cartridge and here is where our tonearm " hunting " begin trying to find the " magic " match.

Btw, I don't have any experience with the Royal. Which yours?

Dear Axel: That there are other several factors that contribute to distortions related with the stylus shape.

Now, I posted: " IMHO I think that the only way to realy satisfy our curiosity on the subject will be to make distortion measures everything the same but the stylus shape. "

This coud be the only way to have aisle the stylus shape subject.

+++++ " As to having --- own "ideas" based on ones knowledge and experience ---- isn't that what gaining 'understanding' is all about? " +++++

in this case an according with the thread title it is not enough we have to measure those distortions that comes from the sole stylus shape differences, well at least is the way I understand that: but you are your own boss.

Axel, do you realy want a true precise/absolute answer or only to have an idea?, what do you want?

Anyway that's my point of view.

Dear Axel: Everyone can have its own " ideas " about as are their know-how and experiences on the subject.

In your thread you want to " aisle " the stylus shape against distortion and here like in other audo devices the stylus shape is not an aisle factor, there are several other factors that contribute directly/inderectly to that distortions, so in someways is useless.

IMHO I think that the only way to realy satisfy our curiosity on the subject will be to make distortion measures everything the same but the stylus shape.
From what I know ( maybe I'm wrong ) those kind of " scientific " studie does not exist ( even with cartridge/stylus designers. At least no one that I know publish on the subject. ) yet and IMHO only this precise information realy can help to fulfil our curiosity about.

Dear Axel: No it is not rhetorical. I already posted my " ideas ".

The point, I think must be critical for cartridge/stylus designers. I can tell you that when we ( Guillermo and I ) will in deep in our cartridge design ( we are on the first steps now. ) some way or the other we will make the research about till our resources permit.
Maybe some one already do it and I hope that could share with the audio community.
