Uni-Protractor Set tonearm alignment


Looks like Dertonarm has put his money where his mouth is and designed the ultimate universal alignment tractor.

Early days, It would be great to hear from someone who has used it and compared to Mint, Feikert etc.

Given its high price, it will need to justify its superiority against all others. It does look in another league compared to those other alignemt devices

Dear Syntax,
I really can't see even one reason for your post.
Your first photo is a paradigm that can not happens. Never!
Your third photo also shows a misalignment. Maybe a slight but true. Any difficulty that arises always, it has to do with the cantilever alignment and not with the stylus. Moreover, the centering of the protractor's needle to the pivot point, is by far the most difficult part. At least, this is what I want to believe. It is so obviously basic & easy to put the stylus into the hole, that about your third photo, I prefer to believe that you take a shot from some strange corner that can cheat the eye. The point of discussion is the prefered alignment, together with the accuracy of the protractor. The skill of the user to follow the offered precision is irrelevant. I'll take your examples as were about the difficulty for a successfully precise alignment that offered to the user by the Dennesen, in contrast with the more easy UNI-Protractor.
Dear Geoch: IMHO Syntax is a marketing manager with a way different knowledge-ignorance level that many of us.

I agree with you and I can add:

Baerwald and Löfgren B approaches differ only in the overhang distance ( that changed the PTS distance with the same EL and offset angle. ), this overhang difference is around 0.4mm that's a lot longer than the Syntax sample/pictures ( as always great photos. ). Both set up geometry approaches are good ones with in theory a little different kind of trade-offs.

Even if everything is " perfect " and the cantilever aligned, re-set of SRA/Azymuth set up, PTS distance, etc, etc. all these we did it in static status when the cartridge stylus hit the LP on playback all we know what happen ( we already discussed in this thread. ) through the imperfect LP medium.

How this Syntax could hear any difference ( if any. ) in quality performance that he can attest was because the cartridge stylus position changed 0.1 mm?, IMHO and with all respect makes no sense other than commercial corruption.

I think that a good product like this protractor does not needs this kind of " help ".

As you said, the protractor makes things more easy and this sole characteristic is important.

Regards and enjoy the music,
Raul.

Syntax, I agree with Geoch and Raul.

I do not see the point with your posting.

Anyone with very little skill can position a stylus onto a point, so this kind of misalignment would be rare.
Nobody cares about the dennesen tractor misalignmnet vs correct alignment, unless you are doing a vaild comparison against the Uni Tractor.

After all, this is what the thread is about.
Dear Geoch, you state:

"the skill of the user to follow the offered precision is irrelevant"

what does it mean? As most of us do know and have learned how to align a cart & tonearm combination properly I have seen and heard many times inproper alignments. Having used for many years the Dennessen I know that you need a good time and some patience and also some skills to bring the needle into the hole.

Unfortunately what we are missing in our hobby are learning or training courses on proper alignment. if you don't have a good trainer/coach/friend not only giving you shows or demonstrations (I attended once Mike Fremers demonstration at the High End but this is theory demonstration
only!) and you are not doing it by yourself under supervision using a good tool you will always struggle or feel insecure. Do ask most people out there - not the hardcore guys - how they feel about this.

maybe this is what Synatx tried to demonstrate. 1mm correct or not, if you have the chance to match it exactely why not going for this?
