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 👀

Dear @dover :  """  Halcro you have suggested before that effective mass does not have an impact before but you are wrong...""""

obviously totally wrong but is not his culprit, things are that he just can't hear it: it's now aware of it. This is the problem with this gentleman is that unfortunatelly is a self negation/deny for him and just is not willing to change, willing to learn.

Dover, what you said about you and every single true audiophile learned when we studied  audio in the very first steps: kindergarden.

Some of us are way sticky to " something " and we can't do nothing to be unglued.

Regards and enjoy the music,

Dear @dover : You posted to richardkrebs:   """  That statement is not correct... """

and he posted:  """  Because if the movement of the cantilever (at the stylus end) is not the same, then the stylus is not following the groove..."""

things are that never is the same because the stylus cartridge follows the grooves in tiny different ways. 

Compliance, cartridge cantilever/stylus effective mass and output are different as is each cartridge tracking abilities, amplitude can't be exactly the same.

Regards and enjoy the music,

yes, yes of course. I was not and Halcro was not talking about individual carts arms
We were talking about different families of carts, MM and MC

Further, I did not use the word "Exactly"

cheers

Seems to me this conversation is getting a bit strange. Someone is saying the mechanical amplitude of cantilever movements should be the same for different carts, or types of carts?

That's a bizarre notion. Maybe you're looking at the stylus end of the stick? What really counts is the generator end. That's where the cantilever delivers the goods - excites the generator and converts mechanical movement to electricity.

Compliance is a measure of springiness. Would you expect 2 cantilevers with different springiness, made of different material, and of different lengths, to vibrate/resonate and deflect the same? 

I think the reason you can get decent results with a 64S, is because the arm/cart resonant frequency with a 'normal' cu cart goes down rather than up.  If you have a stable platform you can tune the combo with compatible headshell, tonearm wrap, damping, etc. and whatever works as long as it tracks and your woofers aren't jumping out of their baskets.

If you use a low cu cart on light arm, the resonant frequency goes up and approaches or enters the audible band which results in intermodulation distortion. IMD can sound euphonic here, reinforcing the bass or midbass, although it can cause involvement many octaves above the resonant frequency.

Flieb.  Yes I was talking about movement at the stylus end and I'm pretty sure that this is what Halcro meant as well. 
There is the very real risk of us all talking past each other here. 
To rephrase my original question to Halcro. Why would a MM cart have any difference in stylus movement than a MC? This assuming both are set up correctly in a compatible tone arm. There was no hidden meaning in my question. What happens at the other end of the stick is, of course, a whole different story. 

I could not agree with you more on your comments re resonant frequency.

cheers.
