According to theory, moving coils should be immune to capacitance changes. But in audio, theory isnt always right. Trust your ears and leave it set on the setting that sounds best to u. Yes moving magnets and moving iron cartridges behave the same way and they are very sensitive to capacitance, some require low capacitance and others like the shure v15 series require about 400pF to get the flattest response. Check the cartridge mfrs. instructions for a good starting point and then experiment with different values until u like what u hear. As for the guy with too much capacitance in his preamp, I just heard of a way that u can lower the total capacitance by soldering a small cap in series with each of the tonearm leads. When caps are put in series with the circuit the total capacitance drops just like resistance drops when resistors are put in parallel. You can use ohms law to determine what value of capacitance u need to put in series with the phono leads. I have never tried this yet, but it sounds believable according to theory. But in audio theory is not always right! Hope this helps and Happy Listening! Shay
PF SETTING FOR MC CARTRIDGE WITH SUT
I have a low output MC cartridge, My Sonic Lab Ultra with 0.6 ohm internal impedance. I am using a My Sonic Lab Stage 302 SUT which is connected directly to my MM Phono stage. Could someone explain what "PF" setting I should be using in my phonostage? The range in 50-750 in increments of 50. I had read that a good rule of thumb is to take the cartridge impedance and multiply by 10 which would be between 50 and 100 pf? The recommended impedance load for this cartridge run through a MC phono pre is 200 ohms. Look forward to any advice.
