The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL

Dear @dover : look what is garbage is what you posted and that you did not read slowly through my posts where I said: " those numbers shows electrically FR.." and " Electrically this is the FR response loaded at 22K... "

In those reviews what you look is not the electrical real FR of the cartridges but what through a not even D2D recordings by JVC and CBS showed and where the reviewers used different tonearm/TTs, yes all those has all de " defects " off those old time about the LP recording tests and what you listened with out the cartridge Dynamic Stabilizer is not what the reviewers did it.

Other thing that you did not read it is:

" Please bear in mind that the calculator is based on an electrical model only. It cannot make any any assumptions about about what is happening on a mechanical level. Resonances of the cantilever, which can contribute to the frequency response and sound of a phono cartridge, and other mechanical effects are not taken into account. "

What @lewm , me an hundred of audiophiles are enjoying today with all those vintage cartridges are doing ( loading at 100khz. ) through almost today top tonearms/TT or top vintage ones along many oher system improved characteristics over the reviewers or even/maybe you in those old times.

Those gentlemans and lew/me know exactly what we are talking today and we are doing in each one home system, you can be sure that your " ears " are not way better than us and you can be sure too that my thousands of first hand experiences about could even you experiences.

" 100k will generate a large high frequency peak.... ", electrically not really because it shows around 1+db at around 10khz, 2+db at 18khz and only 3+db at 20khz going down fast at 25khz and you know what? that " peak " contributes to to in some ways compensate for the filter used at 50khz ( around it. Neumann pole. ) during the recording LP sessions to help/impede the cutting head goes burn-in.

And those 2+/3+db are numbers that goes perfectly with what ( very long time ago research with Ortofon Golden Ears panel found out. ) Ortofon did and does where the MC Diamond or Verissimo has a 2+db down there and this deviation is make on purpose by Ortofon. Period.

Also, the idea of loading at 100K ohms vs 47K ohms should not be considered in isolation from the load capacitance, which is what I was getting at when I mentioned that 47K ohms with ~200pF and 100K ohms with ~100pF give about the same RC constant. Or in the case of the Grace where Grace recommended 400pF with 47K ohms, 200pF with 100K ohms (about where I am for R and C) is equivalent, at least mathematically in the equation for resonant frequency. I think 99% of manufacturers will recommend 47K ohms for R, because 99% of MM phono stages come equipped with a 47K ohm load resistance, and why send the customer into a tailspin by recommending some other resistive load?

look what is garbage is what you posted and that you did not read slowly through my posts where I said: " those numbers shows electrically FR.." and " Electrically this is the FR response loaded at 22K... "

@rauliruegas 

I actually did read your post carefully, and the electrical parameters and assumptions that you used in your calculations are wrong.

Good for you. Stay calm. Bye ¡ ¡

Mijo, don’t forget to add in the input capacitance of your phono stage. In proportion to their gain factor all phono stages present a capacitance, both tube and solid state types, especially those with op amp input stages.
