Thales Simplicity tonearm review in Stereophile.

Yeah, the alignment would be way off. On the other hand, if you could make up for that, by changing the P2S distance on a table with a pivoting arm board. Having the headshell backward would allow you to get to the cartridge screws, and you would be able to adjust alignment like a normal arm. Instead of using that funky alignment jig it comes with. Unless having the headshell plate backwards would throw it's geometry off. Which it probably would.

The Simplicity is an articulated tonearm so its geometry has to be exact to work as intended. The stylus has to be exactly below the pivot (on the left armwand bearing) on the headshell in order to be tangential tracking. Any misalignment will throw everything out of wack. It's not supposed to have overhang but the wrong headshell installation push the stylus about an inch forward so it creates overhang and would throw off everything. You cannot treat it like a normal arm because the headshell pivots and the armbase also has two pivot points which makes it a tetragonal geometry.

PS. I alerted this to Thales and the designer replied back saying the mistake was corrected before the sonic review but the photos were taken already so they printed it as he said "it's the French way of life..." A funny dig on c'est la vie!

With this headshell adjustment there is no right geometry and it's impossible to get any kind of good results.

Amazing this Thales controversy!

Hiho why do you say that? Just install the arm following Thales' instructions, align the cartridge in the easy to use alignment tool and don't tamper with the factory settings. It's quite simple. If you can manage those simple steps you have an arm that tracks very well and has no inner groove distortion.

Profitournesol, my post was referring to Sarcher30's comment above. He said:

"Having the headshell backward would allow you to get to the cartridge screws, and you would be able to adjust alignment like a normal arm. Instead of using that funky alignment jig it comes with. Unless having the headshell plate backwards would throw it's geometry off. Which it probably would."

He pretty much answered his own question. So bottomline is that when the headshell plate is backward, it is impossible to get the geometry correct.

The stylus has to be exactly below the pivoting bearing on the left wand to be tangent.
