But if you read my first intervention, where I introduced the preamps I was considering to build and compare, you will notice that I didn't mention cartridges anywhere.
The anti-RIAA at the input was just part of the simulation, to look at THD, FR response and noise. The differences you talk about between bjt and fet that you were interested in did show there or should show.
It was then that others, like you, Marcel or Hans introduced cartridges and then clicks to show how they behaved in preamps.
But I have no problem in opening another thread, talking about how to model cartridges to get realistic response from the simulations, how they influenced things when included.
i already pointed out where the discussion split about cartridges here:
https://www.diyaudio.com/forums/ana...vs-bjt-input-phono-preamp-40.html#post6369068
and also found that Billshurv have a huge topic on mechanical cartridge resonances where probably Hans is the man...
mechanical resonance in MMs
Now what's interesting is that there are 168 pages of that topic and Hans is comming in this topic with an "approximate" model....Shouldn't they completely have elucidate the subject in 168 pages ?
There are at least 10 pages rambling about a thing that wasn't set completely in 168 pages of another topic while Shure v15type III is the most talked mm cartridge of all times.
So maybe you should move this discussion there cause i won't agree with this topic change into another 100 pages of theoretical sterile discussions about something else than the topic's name is!
Besides...i think that the bipolar vs fet input phono pros and cons were elucidated already by MarcelvdG and Hans. Nothing really to add on that.

That's not how DIYaudio is arranged. If you don't like it find a forum with hard line moderation that is populated with people who share your views.
You're not telling anything technical here or in other topics...you're just constantly looking for quarrel! The only technical thing i saw written by you in two years was how many cartridges you own!
Besides this forum have a problem in that some topics are just so diffuse that you can't follow an instructive line...
Have you ever followed every page of a 100+ pages topic? We all do some offtopic comments from time to time, but you seem like one that wants to transform every single topic in a complete mess ...
Is there a single phono oriented topic whare you didn't "contributed " in the last two years?
no YOU have a problem. There is a solution to that problem.
Yes. So?
Oooh speech marks. Thinly veiled insult. Will be treated with the contempt it deserved.
Neither do you, other than copy/pasting chunks of schematics (that you don't understand) from commercial products documentation, posting claims without any solid justification, and honest statements about your inability to follow any serious technical argumentation. Once again, this is trolling in my book.
At least i know the virtues of those commercial designs that have 10 times less components than your designs for the same perceived performance...Before trying to explain where i got wrong with those schematics you didn't ever saw before , try relearn Romanian.It will do good to your soul! Don't worry, nobody will think you're from a third world country with a wild politics where people's agressive attitude is a must in order to survive !

It was all about the absolute noise with cartridge impedances , all the other performances being at the merci of the sheer topology .Marcel has pointed out everything you need to know on that .
The guy who first showed me how to separate the Shure cartridge load from the antiriaa network output impedance (yes...i'm that stupid!) also had this article on linkedin which you might like consulting as it throws a different light on the influence of bipolar input to the cartridge:

Just another chunk of an old schematic that i can't understand without syn08 solid knowledge of the Universe ,but you won't find it easily , courtesy to KCP , the E.F Taylor phono preamp:

Plenty of jolly fun looking at the howlers in #411 schematic. Is everybody happy about the way the opamp's VIN+ terminal has been handled?
but if you really insist...i even made the difference higher ...for 2v-1v supply noise you can easily have about 3mv output noise...is it good enough for you guys?

For what it's worth, I agree with dreamth. This thread has moved completely off topic somewhere around post 264, so splitting it could make things somewhat less messy.
Every thread goes this way. Several first posts are on topic, then it goes to mess. Cannot be different. Such is every forum, for the reason there is a full mix of knowledge, ignorance and strange ambitions.
