Uni-Protractor Set tonearm alignment

Dear Raul,
understand very well. maybe we all have spent a little too much in too many different solutions regarding finding the exact geometry for our tonearms. I became happy with the Dennessen but did also see the limits for other installations when getting to know that some data inputs from some manufacturers for their own arms were not the right ones for special cartridges we are using. Therefore the situation for someone who deals with more than one tonearm/cart was calling for a universal approach. I have big hopes that the Uni-Pro is a good answer for those multi-users but I also wait with an assessment until I have made my own experiences with the sets ordered.

Dear Henry, knife-edge bearing tonearms do not like cartridges which do transfer a lot of energy into the armwand. Thus SAEC tonearms - despite the fact that some do sport a pretty high moving mass - in general do fare better with cartridge featuring high compliance.
So expect your WE-308 to perform pretty well with most of your MMs, but not with a FR-7.
As I still do favor LOMC and some with really low compliance, the not optimal energy handling abilities of the knife-edge bearings were abandoned in an early design stage.
To achieved my goals I needed very hard and rigid bearings and an armwand which can transfer energy ASAP without torsion or inner resonance.
Cheers,
D.

Dear Daniel,
Interesting?
How about unipivots?
Do they like low compliance cartridges in your opinion?
Cheers
Henry

Dear Henry,
there is - IMHO ... ;-) ... - a direct correlation between low compliance and the amount of energy transferred into the tonearm. Certain bearing principles can handle that energy better - others fare less well.
This is kind of a sensible topic - I am a bit reluctant to discuss toneram bearing principles in public, as I do not want to step on any toes.
If o.k. with you, I will address your question in detail tomorrow in a PM direct to you.
Cheers,
D.

"Perhaps you should start a specific thread about the different SME arms or do a search in the archives. There is lots of information regarding these arms. You could also email Sumiko, the US importer."

Peterayer,

I am aware of all that. I have been participating in online forums since the early 80's when we had to dial in on 300 baud modems. I thought this illustrious group could help me avoid sorting through much irrelevant material. If you are an admin here perhaps you can give me Audiogon search tips. Even Google gives lots of trash. Although their recent changes have helped.
