The Palladian-A step beyond

The new cartridge from Acoustical Systems may finally be the LOMC to fully realise the theoretical advantages of the genus.
And convince those long-suffering audiophiles to whom the 'modern' MC presentation has been anathema to 'live sound'....that the realism of vintage LOMCs like the SPUs and FR-7 series has finally been recaptured 👀

Wouldn’t the amplitude (movement) of the cantilever be the same for both families of cartridge?

Not necessarily. In both cases, the stylus follows the groove, but there could be differences in the extent to which groove modulations move the cantilever relative to the tonearm and the tonearm relative to its pivot. A stiffer cantilever suspension could well mean less cantilever movement and more tonearm vibration.

maybe the reason is down to incompatable effective mass of the arm cart combo?

That's what I think most folk believe, thus putting more stress in the tonearm......
I'm still not totally convinced 🤔
Surely attaching an accelerometer to a tonearm to produce graphic evidence of the stresses would not be difficult?
I'm sure Continuum did....

The FR-66s has the highest effective mass of any commercial tonearm produced.
If there were no audible compatibility issues with it, plus its little brother FR-64s plus the DV-507/II plus the SAEC WE-8000/ST.....I can't see effective mass being the reason....?
At any rate, it was not a low-frequency problem or arm vibration that ruled out the other tonearms.

Sampsa 55, ''Implies'' is logical conclusion, not a conjecture''.

This is correct provided we provided the premisse from which

the conclusion follow. The logic state that a conclusion is

true if the premisse is also true. But logic does not decide about

the ''real truth''. Meanings or sense are about languge such that

we understand what is stated. We need in addition the reference

to the reality . The so called ''correspondence'' between statements

and reality. However ''corespondence'' should not be seen as

''identity relation'' . This was the reason for Frege's curious

invention that statements refer to truth values: the truth OR

the false. Wittgenstein stated: ''for two things to say that they

are identical make no sense and to say that everything is identical

with its self say nothing''.
