Tonearm recommendation
Lewm, Is this UNI like using 2 protractors? Seems to me no individual protractor can align for both Stevenson on the inner and Loefgren on the outer. Regards, |
Dietrich’s UNIProtractor, which I also use, is set up to align to his UNI Din standard which was discussed earlier in this thread. The UNIProtractor is a very accurate system but does rely upon being able to align with the tonearm pivot very accurately, while this can be performed very easily on arms like a Kairos which has a defined pivot point it can be much harder on an SME IV say where the precise pivot point is hard to spot A review of the current iteration of this tool is here http://www.theaudiobeat.com/blog/smartractor.htm |
Now that I think about it, I asked a dumb question. Of course a single set up protractor can have any 2 nulls drawn or etched on it. I was thinking from the standpoint of protractor with a single standard alignment, hence the question. Is that Audio Beat a review or a marketing business? Probably both. Gregory did a nice sales job with only a deception or two, but the only thing that really interests me is the UNI-P2S, and he only mentioned it. Follow the link and you have to download. It's probably a fancy Dennesen tonearm locator, just as all these alignment grid/pivot pointer protractors are based on the SoundTractor, only they're better. Thanks for the link Folkfreak. Those Dertonearms look interesting. A little pricey maybe. Regards, |
Yes, the UNI is "pricey". My only beef about cost is that, at that cost, it does not allow measurement of P2S with any accuracy. When I brought this up, after purchase, I was offered the opportunity to buy an accessory which fills that void. However, the additional cost of that accessory was half again as much as that of the UNI. I demurred. I subsequently "inherited" a Feickert alignment jig, which has a well calibrated arm for accurate measurement of P2S. That's what I use now. In subsequent versions of his protractor, DT seems to have rectified this deficiency while also reducing cost. The UNI was his first go at designing a protractor, evidently. Still, in all, he thought of every other aspect of the problem in designing the UNI. Nice work. Fleib, It's not an arc protractor; it's more like the Dennesen, of which I also am an owner for the past 3 decades. But to say that the UNI is like the Dennesen is to say that a Ferrari is like a Miata. |
fleib, when you say "fancy Dennesen tonearm locator, just as all these alignment grid/pivot pointer protractors are based on the SoundTractor, only they're better." do you mean the others are more accurate than the Dennesen? Or easier to use? Something else? I'm not at all familiar with the UNI and I've at least looked at a Feickert at audio shows. But I've owned and used a metal Dennesen for nearly as long as Lew. So long as the pivot point of the arm can be located I've had no reason to be disappointed with my cartridge set ups. And yes, I'm satisfied with the Baerwald alignment. If I'm out of date I'd appreciate being updated. |
