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

"Joel had considered the idea of providing a Mint protractor with the tonearm, but we see examples above of individuals who cannot relate to this wonderful tool."

I certainly can relate to this tool. I also can relate to the fact that with the supplied 10x loupe, with my cartridge, it is not practical as I can't get a good view of the cantilever. So it doesn't matter how accurate Mint may be. Of course with another type of loupe, it might work beautifully.

If Dertoarm's allow for easy view and the alignment is precise, I think it will be a hit. Plus, I've been wanting to try out Lofgren.
Same 10X peak lupe I'm complaining about in my earlier post. Put it on top of an eraser just like the pix on Mint website. It fell down, rolled and bumped the cantilever. Luckily no serious damage done. Derto supplied magnefying glass seems will do the job.
Dertonarm,

Thanks for the clarifying points. You mentioned one point which may have been lost on folks, because everyone's attention is captured by the design of the Uni-tractor and your selection of geometries. I want to highlight your point:

This is probably a better investment than swapping cartridges, which won't show us anything new (at the end of day).
All too often (and in every area of the signal chain), we as audiophiles neglect the importance of setup, as our attention is always captured by the latest and greatest component.

The individual debating the purchase of the next $1,000 cartridge (we don't have to get to the pricing $tratosphere) would do well to ask himself the following question:

"have I provided my current cartridge every opportunity to succeed?".

If the answer is "no", you are randomly wandering about, and are depending on luck to reach success (not that I'm against a bit of luck here and there ~grin~).

Cheers,
Thom @ Galibier
Thank you Syntax for this excellent post.
Replies for developing a state of mind like this one, can help us maybe even more than the actual product !
There was a thread 'Why more then one tonearm?' or something. Well we have the answer as well as some kind
of Copernican turn. We need to measure the distance from
the lead out groove till the spindle and reorganize our
LP collection accordingly. Assuming,say, 4 categorys corresponding to 4 different tonearm geometrys (otherwise
5) we will be able to use the right tonearm with the right
LP's. One need to measure first to decide how many tonearms
one will need , mark them derafter accordingly and then
apply all the acquired knowledge by each LP we intend to
play.
