Tone arm length

Chiming in just to say I’ve been following the thread and learning, thank you.

I’m about to set up my 12” on as I have a new cart coming. 
 

I have some Wally Tools arriving soon.

Dear @thom_at_galibier_design  :  " I still don’t know why they fixed the overhang "

Overall the japanese vintage tonearm manufacturers really did not care to much about or had a misunderstood on the alignments subject.

I owned/own over 12 of those tonearms and after took in count that the specs can't " even " the Lögren alignments I just took the EL specification and set up with either of those Lögren alignments.

The Japanese have throughout the 20th Century produced innovative designs in all areas of Technology, to the point where they were a World Leading Authorities.

Like all Business Models based on Technology there is the High Turnover Market and the Bespoke Market, Japan pretty much had both Markets sewn up and was proved to be very difficult to penetrate.

They did also contribute to a rise in Home Grown Markets cashing in on the Trends that Japan was so successful at bringing to the Mass Market Arena.

Questioning the design intent behind a range of Japanese TA's is futile as a activity, these designs are secure in their roles and very special to their owners or alternatively witnessed to be endlessly resurfacing as the option that proved to be better than many many others experienced.   

I've 9" and 12" Jelco 850 arms on a well-fettled 401 so I can make direct comparisons. Bass is a little tighter and the overall sound slightly drier on the 9". The 12" has more authority, liquidness and musicality with more dimension to the soundstage.

I have an Innovation [Wood - which is no longer used for the model name]. I have two 12" Universal arms on mine, and I used to have a 9" instead for one of them. Both have Lyra Atlas cartridges. One is the SL (stereo) and the other is the Mono. I use the SMARTTractor alignment tool and Löfgren B DIN alignment for both cartridges, but I spend a bit of time really getting the alignment nailed as perfectly as I can. This is the best sound I have gotten from the TT. I play everything from older (60s/70s) classical records to modern 33 and 45v RPM reissues.
