Uni-Protractor Set tonearm alignment

Wrm57,
Thanks. Not sure what the UNI-IEC is... I am curious. I will have to dig further.

The Baerwald alignment using the UNI-Pro sounded better on the Graham than the Wally and better on the Universal than the MintLP. It also sounded better than the UNI-IEC alignment. At some point, I'll go back and realign again using all and recheck, but I was pretty careful the first time through the process, so for now I'll just enjoy the music.

Dear T_bone, dear Wrm57, let me add some technical parameters to the discussion.
The UNI-IEC features zero points at 116.39 and 67.44 mm radius (very close to what T_bone once named "Dert67" ... ;-) ...).
After radius approx. 117, this alignment has approx. 20 % less tracking distortion due to tangential error then Baerwald IEC and is very similar to Baerwald curve after radius 66 mm.
A very suitable alignment if most of the records played are made past 1982 and feature rather long wax/lead out groove.
UNI-DIN features zero points at 109.52 and 63.49 and is ideal suited for stereo records made in the early days with short lead out grooves/grooved area running close to the label.
Both alignments to pay attention to certain aspects of stereo stylus with decreasing radius and concentrate the focus of minimized tracking distortion on the last 2/3 of the groove.

The long awaited UNI-P2S will finally (sic ...) be introduced next week. It proofed much more tricky to integrate it's function with the UNI-Protractor, but finally I succeeded and will bring something rather unique in both - function and precision.
Cheers,
D.

Dertonarm, will you be offering a stand alone P2S?

Brad

Dear Ecir38, yes - the UNI-P2S is a stand-alone-device.
It features 0.05 mm accuracy and can measure mounting distance up to 15" or 38 cm. It has some unique features of it's own.
The UNI-P2S nevertheless can be used in close conjunction with the UNI-Protractor and offers then direct measurement of mounting distance with 0.05 mm accuracy during alignment of cartridge.
In other words - you can read down the exact mounting distance every moment during actually aligning your cartridge.
It was quite some work to design the P2S so that it now meets the universal approach I was longing for.
I will introduce the UNI-P2S next week and it will ready for order and immediate shipment by end of July 2011.
Cheers,
D.
