I guess I missed this. Can you provide a URL to these notes and charts?
Thanks,

link below to the full review.
The interesting part is the mfr's comments which offer quite a lot of information describing his product. Just page over the reviewer's comments, which I find of little interest, to find the Touraj's comments.

Thanks, Steve.
For some odd reason none of that stuff appears on my computer screen from the original posters link. I just checked it again and I get only three pictures and that's it. But, your link works just fine.
Okay, there is nothing special about this guy's tonearm geometry. He simply uses a different set of null-points than SME.
.
He moves the null-points closer together and trades lower middle groove distortion for higher inner and outer groove distortion. You can do the same thing with any tonearm by aligning to null-points of 68.33-mm and 118.45-mm. If you truly believe this alignment is something special you can download Conrad Hoffman's Custom Arc Template Generator for Phono Cartridge Alignment and set the inner groove radius to 62.827-mm and the outer groove radius 139.66-mm while using Löfgren A with your own spindle-to-pivot mounting distance. You'll get those same alignment null-points of 68.33-mm and 118.45-mm.
There is really nothing new under the sun regarding pivotal tonearm alignment, but since so few people actually understand tonearm geometry, some charlatan like this guy can convince people that his $35k tonearm can magically reduce tracking error by one-degree over any other similar length tonearm. Unfortunately, it's not true and the guy is simply a con man and ripoff artist. The world is full of suckers and some of them are rich and willing to spend $35k for a simple pivotal tonearm with some oddly offset bearings and shining LEDs.
Oh, well. Such is life!
Good luck,
John Elison

John- no need to hold back. Why not just say what you mean?

Well, I was trying to be tactful. ;-)
