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

Genesis168,
I am currently using an early 80s Pioneer turntable with early 80s Pioneer electronics (amps, pre with phono stage and headamp). They provide superlative reproduction of music. They have vanishingly low levels of distortion, and the headamp and amps are probably the quietest examples I have ever heard. And they are black too (except for the TT).

Lots of manufacturers had cheap stuff which doesn't sound great. That included mfrs from all over - not just from Japan. Some also had stuff which competes with the best out there today (and on an inflation-adjusted basis had prices to match the best of today (inflation-adjusted MSRP of the headamp would be in the range of $8-10k)).

Dear Dev, thank you. The 2nd production run of the uNI-Protractor starts in April 2011 and we are already taking reservations, as the 2nd production run is limited edition too. You may request individual UNI-templates for your Reed 12" as well as for the TW 10.5 (in fact, both templates are available, as they were already requested from some customers). If you have any specific questions regarding the UNI-Protractors function or would like to have a look into its manual, please send me a PM and I will be happy to send you further info.
Cheers,
D.

Dear Dertonarm, The most 'variations' relate to the lead
out groove; the distance to the spindle hole. So no need
to worry about the outer groove. The math. is,alas, not my
best subject but it seems to me that depending on the mentioned distance 'many' O points should be possible. From Raul's arguments however I can deduce just 2 possible O points in relation to the 'inside part' of the record:
L. A or L. B. The simplicity of a theory is of course an
virtue but Einstein had some criptic comment about that:
'but not simpler'. Ie. one seldom see any distance mentioned except the most probable(average or?).
I own records with the distance of 10-4,5cm.to the 'hole'.
I got this result by inspeting just 10 records.So I claim
no 'scientific reaserch' but assume that others my own even
more 'extended' distances.
Some'light' for this 'dark part' would be very appreciated.
Regards,

There are many truly fantastic stuff from Japan. I do own some too. What I was referring was their cheap mass market stuff with that rated 0.00000??THD as an example

Complexity is always a challenge in this world. If you decide to live in a more simple world (not a bad meaning at all) you better go for a one tonearm/one cart soltion. There is no need for changing the tires. Nevertheless if one wants to reach the capabilities of Genesis 168 being able driving a Honda as well as a Ford even on different tiers ( also feeling the difference) you may need a good garage or excellent tools.I learned that some of us, Raul too and me as well, are sitting in front of a complex world.

There might be two ways of dealing with complexity. Usually we try to reduce complexity heading for simple solutions. A side effect of this approach is also reducing cognitive dissonance - you start feeling better!

Another way is to develop solutions for different requirements and tackle various applications by using different methodologies. This is something - at least to my understanding - the Uni-Pro approach is aiming at in this special field.

In the end everyone becomes happy. The manufacturer of a gauge adressing requests of potential customers going for a simple solution as well as those multi-users or people wo really care about exact geometry in various application fields. This means: There is no need for a war - at least not in this thread...
