Hello LD - question for you 🙂
How does the cantilever affect the cart plot when its done in free air - i.e. not tracking anything and just suspended off the arm a la George's findings?

A guess but not much if at all, I'd think.Hello LD - question for you 🙂

I think that, for all the wrong reasons, cartridges with low effective tip mass don't have audioband resonances.
Tip mass was worked backwards from observation of the 'top resonance' assuming a certain vinyl spring constant, which value I've lost and can't find again. Now whether that is right or wrong I suppose is a moot point: what matters is that the resonance is clear of the audioband. Tip mass is a restatement of that.

Kerstens covered this topic (or at least some of it) in his article from 1956/57:
Kerstens, J. B. S. M. MECHANICAL PHENOMENA IN GRAMOPHONE PICK-UPS AT HIGH AUDIO FREQUENCIES, Philips Technical Review, Vol.18, 1956/57, No.3
Afair Anderson (from Shure) did a more analytically based calculation of the tip mass (or more precisely the equivalent tip mass) in an Audio mag article, but i´ve to look for it.
Interesting article thank you Jakob (found here http://www.extra.research.philips.c...ve/PTechReview/PTechReview-18-1956_57-089.pdf ) Ah the days when 10g was a low VTF.
I would listen then test. But I've somehow been doing neither on a lot of my ideas so don't believe a word I say 😀
Bastiaans also published a very informative/thorough article about it:
Bastiaans,C.R. Factors Affecting the Stylus/Groove Relationship in Phonograph Playback Systems, JAES, October 1967,Volume 15, Number 4, 389
The before mentioned article from Anderson about the equivalent tip mass:

If someone needs help to get a copy, drop me a note.
