Dear @dgarretson @peterayer : Thank’s for the link.
Now, even that’s not exactly the same the today SME M2-12R is theSME 3012R response where mainly they fixed the main " trouble " in the vintage tonearm because in the M2 there is no knife bearing any more along that SME improved the internal damping and internal wire.
Other than the good look 12" tonearms really can’t gives us a true advantages even its lower tracking error. This example speaks by it self.
Löfgren A IEC standard. Tracking distortion in between/around null points for a 12" against what for me could be the best EL compromise 10.5" and against 9" too:
12 "....... 0.420%
10.5"... 0.485%
9"........ 0.58%
Who in this thread can detect: 0.065% or 0.16% against the 9" difference?
I know I can’t do it. We have to take in count too that at each single mm. the tracking distortion is changing all over the LP recorded grooves:
same premises but 1mm. after:
12"....0.419% vs 0.420% 1mm. before, difference of 0.001% tracking distortion that even a bat can’t be aware of it.
Those measurements are when the cartridge/tonearm alignment has 100% of accuraccy ! !
So where is the 12" big deal? along that this is what the SAT designer says about in favor of shorter arms vs 12"+ ones:
Makes sense the 12" EL tonearm design other that its look?, certainly not for me.
and we have to think in the higher inertia moment in the 12" and its effect in the cartridge stylus tip/cantilever by that added dynamic mass that needs to handle along all the LP imperfections.
THAT GOD BLESS YOU ALL AND YOUR DEAREST FAMILY IN THIS NEW
2 0 2 3 YEAR ! ! !
Sincerely,
R.
