In the end it’s a matter of choosing the right Cart that best fits your preference and directly related to that what type of preamp you want.
I’m still surprised how large the difference in perceived sound between different Carts and preamps can be, not only for MM’s but also for MC’s.
But that’s exactly what makes this road by trial and error to Vinyl perfection such a nice challence.
Now that it became clear in all aspects what Nick has to offer with his solution, yet another nice choice became available.

Here is a translation of the opinion of one of the users of my phono preamplifier - "I think everything in this preamplifier is in its place - the bass is correct, "not meat", and the highs are like the ringing of expensive crystal glasses, and not faceted glasses", the original test is here https://imrad.com.ua/ru/fonokorrekt...vukosnimatelya-s-podvizhnym-magnitom-mm-50452
due to the fact that the dimensions of my phono preamplifier are only 20x45x3 mm, it easily fits even in the tangential tonearm of the Technics SL-M3 turntable - see here https://www.patreon.com/posts/fonokorrektor-cy-103140215

On page 4 we can read "PinkNoise".
What now? A logarithmic sine sweep?
Since when has
CH Precision
been cutting and producing test records?
kindly,
HBt.
PS
The usual approach is to work with the industry, i.e. a renowned pickup manufacturer. Did you seek contact with (for example) Ortofon in your team of three?

In addition to the V-N-A used, I am interested in your entire measurement chain with all settings, i.e. also the DAQ system.
In my dozen test discs there is also such an Ortofon with a band of up to 50 kilohertz,
Oh Nick,
unfortunately I don't understand your language 😢
but your enthusiasm and attention to detail can also be understood in this way.
greetings,

For all identification attempts of the MM system and subsequent transfer to a trivial electrical model, the entire mechanical chain must of course be perfectly adjusted beforehand.
Bearings, arms, the assembly, ... everything must fit perfectly.
Which drive and arm were used for the groundbreaking test? All this information belongs in the pseudo-publication, without all this information it is quite nice, but otherwise completely worthless.
@Hierfi
Are you asking about the meanings for life on our planet or an individual's personal claim to himself? If you would like to find out more about me personally, please contact Lucifer.
HBt.
The meaning of life seems a trivial pursuit... unless one can get back to it. I will leave the questioning to my friend Neitzsche... though I suspect he would be too bored by your friend Lucifer as loath to seek the answers.
Getting to the statement "Bearings, arms, the assembly, ... everything must fit perfectly".
Perfection is a myth. All there can be are models that more or less reflect the reality, and thereupon have more or less value. If you assign value as only upon the reality of perfection then all is worthless. Total nonsense.

If circumstances come to prevail... in one variant of an afterlife being confronted by Lucifer... this might be preferred as opposed to hanging around for the eternity with an entity that seems particularly "needy"... and apparently with no sense of humor. One might hope for a third door. Perhaps an entity that would enjoy sharing a little weed?... has a good sound system?... and an adequate supply of virgins?.... that can recycle virgins if the well runs dry?... Perhaps an entity that would make me much more attractive... so the virgins can maintain their motivation... rather than feeling as used prostitutes pimped out by the entity?...
But in the meantime... turntables are complex mechanical devices that are a marvel in working as well as they do. Having worked on them over the years the biggest improvement in my opinion (as unsubstantiated with not an iota of measurement...lest challenged) was in the manner of "sinking" the base of the tonearm in a medium that balances freedom of motion, absorption and transmissive qualities.
This involved variant rubber materials that in the experimenting was not of a continuous flat rubber material rather more of three spiders reaching out to the perimeter with stiffeners. This was done on a TD125 Mk2 and a Linn Sondek, both with detachable armboards being drilled out beyond the perimeter of the bases of the tonearms. It should be mentioned that keeping the alignment accurate was and remains problematic.

That too. Though I currently use black electrical tape as a damper at "seeming" critical locations around and along the aluminum arm tube of ITTOK's on both turntables. I was referring to the decoupling of two relatively massive entities, the arm and turntable, from bidirectional transmission in what can include high frequencies. This can be highly complex as not confined of simplistic two-dimensional modeling necessarily.
Since Hierfi is wandering a bit through the mechanical dreams of a turntable with tonearm and tonearm base, allow me to post my wish as well.
Mein Traum
Unfortunately I am too poor and my hearing no longer works the way it did when I was born.

But let's come back to Nick's EQ, which offers us a way to equalize the frequency response of the simplest MM.The data is excellent, what is there to argue about now?
In the meantime, Hans P. seems to have wisely given up his campaign. If I didn't already have hundreds of equalizers and was an MM friend, I would build Nick's EQ and mount it directly into the chassis under the tonearm base.
I think that says it all.

Dear Mr. Polak,
schematic ?
will you disclose the details of your equalizer here in the forum? After all, the purpose of the forum is to build and discuss circuit examples to stimulate your /our own thoughts.
Let's measure ourselves against our circuit designs.

You know very well that Jan Didden has the sole right to disclose.
So why don’t you ask him.

So you
- sold the disclosure of your dimensioning, component selection and topology to Mr. Didden.
- have no rights to your own circuit,
Volume 12
Just under 25 dollars is too much for the secret.
Since Mr. Didden and I are absolutely not friends, I will not ask him to reveal the secret.
What do you do with the production files and the BOM without any knowledge of the schematic? Reverse engineering?
All the best!
HBt.
