Used TechDAS Air Force III vs New Feickert Firebird with Kuzma Safir 9 vs SME 20 MK 2

@thr1961     I am not clear how the choice of a purely mechanical component out of direct contact with the signal, like an arm (or a turntable) can have a differential effect on sound when playing different musical genres.

Do please explain.

I like the idea of the Kuzma Safir arm. I like the look of the AF3 TechDAS better than the Stabi R.  I also like the idea of the vacuum system....

But the Stabi R comes in white which I like!  

I wonder how the Safir Arm on a Feickert would be compared to the Stabi R....

Yeah with the white Safir arm it would look stunning

@clearthinker I am not any kind of engineer nor do I have enough physics knowledge to try to answer your question. However, I do know what I hear (and am fairly confident in not falling victim to owner's bias) and I consistently hear what I described earlier.

For a truly technical point of view, Fremer's review is quite complete: https://www.theabsolutesound.com/articles/kuzma-safir-9-tonearm/
