Uni-Protractor Set tonearm alignment

Syntax,
I presume you prefer yours stirred and not shaken. Great photos as always.

Robob,
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.

Dear Robob, I haven't worked with the SME 309 yet, but his headshell features single mounting holes and hardly any option to alter overhang and/or offset. As such it shares the very same "camp" with it's big brother the "V".
The SME V does feature - as Geoch pointed out - better ball bearings and is a dynamically balanced design ( which - at least IMHO - is an important feature in a pivot tonearm trying to set the state of the art ).
The SME V is - among it's brothers and offsprings - still the best tonearm. Due to superior attention to detail and better parts incorporated.
The other SME tonearms are "trickling-down-products" from the SME V.
Cheers,
D.

At last! For first time ever someone has noticed that a dynamicaly balanced pivoted tonearm is better.
I'm wondering do you feel that it is also neccessary (if it might be possible to integrate in) for the cardanic arms (Pluto 9A, Reed, Davinci, etc)?

The bearings are now the same (i.e. ABEC7) on all the Series V-derived models (= Series IV, 309 etc)and have been for a couple of years now.
You can hear this direct 'from the horse' mouth' if you look at a series of videos about SME on Youtube.Here is the URL of the first of the four (all relatively short):

Best regards,

Dear Syntax,
Thank you for your nice photos.
It is clear that for ALL of my records, (your first photo) the prefered TONEARM'S ALIGNMENT is the Loefgren B.
The problem that I'm still have, is that I can't indentify those particular points on the TONEARM'S GEOMETRY, that dictates to a specialised/individual/unique alignment !
Not to be confused with the alignments of the B,L,S, IEC or DIN, (that depended by the way the LPs were printed on vinyl).
I'm really sorry that I'm posting about this again, but I've just figured a possible misunderstanding might occur about my quest.
What I mean is : When you look a tonearm, how can you see those points that require a modification in it's geometry ?
Is that all about setting new null points ?
I don't expect an answer, I'm posting this just to clarify.
Thanks again.
