Thank you, I had missed that. I’m hoping someone will run a test on one of these, preferably the 40. I may do it at some point as I have an Apt with a MC board in it that I have never used.

Fun with vinyl measurements

I do know there are very satisfying/'great' sounding MM, HOMC, and LOMC cartridges that folks could be happy to live with long term.
But having listened to all 3 variants, and I'm going out on a limb here, I think as a very general rule, LOMC cartridges sound better.
I don't know why, and can't pretend to understand the technology, but in my very basic understanding, coils are lighter than magnets, and when cantilevers have to move either as impelled by the contours of a record groove, lighter (coils) is niftier than heavier (magnets).

By that logic, MI/MP carts should potentially sound even better, as the moving mass can be even lighter than MC.
Little long, but gives a whole lot of information and knowledge for the interested. I can highly recommend it.
Doubly not true that MC have natively lower ETM than MM or that low ETM primarily affects tracking ability.
Can you tell these apart, let alone which is the MC?

Indeed, talking about what is better on a very specific aspect (in the sense of stating 'facts') in a vinyl measurmenent topic without actual measurments or blind testing results is kind of moot.
If you have certain experiences, then post those experiences (as in the files you listended to) so that others can verify or shed their light on them.

I'm going to ask what may sound like a paradoxical question:
How does one quantify how much of a noise floor below / SNR greater than that of LP groove noise itself is a good benchmark?
My subjective method is using headphones:
If, at normal listening volumes, I lift up the stylus and hear no hiss vs listening to an a cappella LP track where I hear the groove noise in the silent parts, then that's "pretty good". This indicates that the limiting factor is not my reproduction chain, but vinyl itself.
But is there a more measurements based answer?

The Ortofon values were better by about 1.5 dB

I thought this was interesting, listen to Peter talk about MI vs MC when it comes to moving mass.

Hurm.
Did the resonance test (HiFi News test LP) on the ART9XA and got 9 Hz.
Pro:
9 Hz is just fine, and that's what really matters.
Con:
Working that into the compliance calculators using my setup (total effective mass of 22.4 g) gives an unexpected result of about 14 mm/N.
Although, if I try to back-convert it to Japanese 100 Hz cu, if I divide by 1.7 (mid-range conversion estimate):
14 / 1.7 = 8.2 cu
Versus the ART9XA published spec of 10 x 10-6 cm/dyne (100 Hz)

Did you retail your ART9XA or is it original?

What are you planning to test with it and how?

Nice, Original or replacement stylus?
