Dear Geoch: Graham unique?, well it is the same with SME V or other " unique " tonearm/cartridge geometry set-ups.
IMHO the only " unique " that has all those " unique " set ups are higher " unique " distortions and that's all.
Geoch, you can explore new things in the subject ( I love to explore and that's why I'm where I'm. ) but here is only mathemathics and only if you have a proved mathematical new " process " could change what we have today on that subject.
This is not that you can do it " by fault " or because " you think " is better some other way.
Now and IMHO, like with the Graham and other " unique " tonearm set ups: that a higher generated distortions likes you or likes other people does not means is right: it means only that you and those other people likes HIGHER DISTORTIONS and that's all.
You don't have to believe me, please put those " unique " tonearm set up ( any ) parameters in a " calculator " ( like the VE one. ) against the öfgren B ( IEC ) one and you can confirm what I'm saying.
Goech, distortions are not only gernerated by cartridge/tonearm tracking or tonearm/cartridge geometry set up, things are more more complex than that.
There are several other factors that " determine " any tonearm/cartridge quality performance level, this subject already was discussed in many other threads in the past.
Between those other factors are: type of tonearm pivot bearing, bearing build material, tolerance level on that bearing system, tonearm effective length, tonearm build materials, cartridge whole characteristics on compliance/stylus shape/MC or MM design/body build material/cantilever build material/etc/etc, arm board build material, etc, etc, and I can go on and on on this factor list.
I don't know where you want to go. Intrinsic tonearm resonances and cartridge resonances has almost nothing to " see " with those geometry equations.
IMHO if a tonearm was designed with a " unique " geometry set up equations on mind with greater distortions due to that geometry " unique " set up and even if you like it for me that tonearm design is a faulty one.
A good tonearm design must left ( very clear and precise. ) that you can discern between different set ups and not only that but that you can be aware that a higher distortion geometry equations set up almost always have to sounds with those higher distortions quality performance level, other way IMHO that tonearm design is not a good design.
Geoch, IMHO here it is not what we like but what is wrong or good/right.
This time and in this subject I'm with what is right. What other people could think on the same subject does not affect what is right because you can't change ( for the better ) that: 2+2=4.
IMHO your example of Technics/B&O has no aplication in this subject because we are not speaking of technology but mathematics: elemental mathematics for say the least.
