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

I've been spending some time with my relatively new UNI-Pro this weekend, aligning an A90 on a Graham Phantom II and a Benz Ebony LO on a Clearaudio Universal arm. I also a have a Wally and MintLP for these arms, respectively. After some initial getting-used-to, the UNI-Pro is simpler and quicker to use and I prefer the results. Checking UNI-Pro Baerwald against the arc protractors, the alignments are not identical despite the fact that both arms (and their protractors) are based on Baerwald geometry. This discrepancy gave me some pause at first, since I've always relied on the arcs. However, I find the sound is notably better using the UNI-Pro. It's deeper, cleaner, more detailed, more relaxed. I'd conclude that means the alignments using the UNI-Pro are more correct. I should add that I prefer the Baerwald template to the UNI-IEC template. It just sounds better to me. Nice job, Daniel!
My templates are labeled UNI-IEC and IEC Baerwald. The former is Daniel's recalculation of the Baerwald geomtery, as I understand it.
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.
