Curved and Straight Tonearms

Dear @lewm : "   I tend to use whatever alignment was in the mind of the person who designed that particular tonearm.. "

Lewm, sorry for my ignorance and if you can please explain me the direct relationship between tonearm design and choosed alignment. How that choosed alignment can helps to stay with overall lower tracking distortions against other alignment type?

Knowing you it has to exist something extremely critical that you are aware of and that I'm taking in count and always is a learning day and as always I'm willing to improve my ignorance level.

Thank's in advance.

@bimasta: Btw, LT tonearms are not free ( in more or less way/levels. ) of the influence of those parameters I mentioned.

Dear @lewm : Even that is out of my mind and that today makes no sense to me ( but I can be wrong and that's why I ask you about. ) that a tonearm design be designed around a specific kind of alignment type y found out that the vintage Japanese tonearms stays around Stevenson A alignment and why mI said " around " because things are that the alignment numbers they gave are non perfectly accurate but only near the precise/rigth alignment calculations. I think only the SAEC 8000 is near LÖfgren A calculations but non-accurated one.

So, seems to me that they did not took enough care about and this kind of fact only says that tracking distortion levels are higher that what you could think.

It's no surprise for me that I found out these kind of non-accurate tonearm set up numbers in almost all japanese tonearms and only confirm what I posted here and that in the " old times " there were a not very clear of the importance of accuracy in the tonearm/TT/cartridge overall set up alignment.

That is funny Raul that you keep repeating this silly made-up "fact" when I have already proven to you in this very thread that this claim is wholly mistaken and yet you feel a need to keep repeating it as though you are some visionary who has brought the importance of proper tonearm alignment to the world of audio and that we should all be so grateful to you for sharing your wisdom with the group. I guess real facts aren't necessary when your world of "facts" includes such funny fantasies I suppose this is  the nature of "fake news."

Dear @lewm : In all japanese vintage tonearms and even today the set up specifications are jus totally non-accurated. Dynavector is a clear example on that when states 15mm. for overhang and even that is near Stevenson A calculations is out of it as is too the offset angle stated by them and it’s does not matters if we choose IEC or DIN for the calculations.

Obviously that these kind of facts tell us that if we are following the tonearm manufacturer set up specs then we are totally wrong and what we have are higher distortion levels.
Of course that’s not our fault to follow the manufacturer instructions. We assume that what they tell us is what we have to do.

I already check all the information from the manufacturers on all the japanese vintage tonearms and no one is accurate about.

All those facts along the " terrible " misunderstood on the subject by that reviewer ( MF. ) confirm that " people " ( including audiophiles. ) do not cares seriously about and maybe they did not because they do not understand the 1938 Löfgren great mathematics studies, its premises and critical importance.

Again, accuracy is the name of the game in TT/tonearm/cartridge alignment with any kind of tonearm design.

lewm, I don’t know if you remeber that I told you that for my 505 set up I used Löfgren alignment with better results than whit the Dyna set up specs. Well, there are very good facts/reasons about.

All those facts can tel us that maybe don’t exist two analog rig set up that gives same distortion levels using same TT/tonearm/cartridge with the same alignment type due to those inaccuracies on the overall set up. Where differences in set up means different quality performance levels.
