SAEC 308N vs 308SX

Dear Lew, 'Dear Nicola or anyone else' is not to the liking
of my 'super ego'. I am alas not an expert in kinematics, have, to be honest, no idea what 'kinematics' means so you are overating me in one aspect of the issue while underating me in some other. My idea is that you should design some
other tonearm base for your second arm on your beloved Kenwood.Ie this SEAC enigma is developing from bad to worst.

Dear Nicola, I do not think so badly of the SAEC 308, just because of the weird geometry. As I said, the very small angle of offset of the headshell (12 degrees) means that there will be less skating force than for any of the standard geometries (where offset angle is at least 20 degrees). This may mitigate any issues with tracking angle types of distortion. Also, I have the RS Labs RS A1 tonearm, which has NO null points across the surface of the LP, and sounds excellent. So I am not so concerned about tracking angle distortion per se. Anyway, based on what Raul wrote, the 308SX, 407/23, and 506 are "cousins". But now I am thinking that maybe the "23" refers to the angle of offset of the headshell. Twenty-three degrees would correspond to Baerwald or Lofgren. In that way, you are ok with your 407/23. Maybe this is also why the 407/23 is so costly now, compared to the 308s. In fact, it would be informative if you can take a protractor and estimate the angle of offset of the headshell on yours.

Dear Lew, This '23 offset angle' by SEAC 407/23 was exactly the story of the Australian importer of the SEAC brand who seems to be at present an succesful designer of HIFI gear Switzerland. If you persist I will search for his name. But Daniel scared me (nearly) to dead with his Kantian way of judgments. I am probable more sensitive to
German threatening than you are. But you are even messing with those 'transfomerless amps' which seems to need at least 1000 spare tubes. Is there any space in your cellar
for some wine btw?

Regards,

Dear Nandric, to ease your mind and save the weekend: .... 23° off set sounds perfectly fine for a 9" effective length pivot tonearm ... ;-) ....
Cheers,
