Is there a list of cartridge capacitance?

Dear Almarg: Thank's to bring those links that I'm aware of.

A>s I posted, I made and have experiences changing capacitance with LOMC cartridges and I can't remember changes on quality level performance. I'm not saying that capacitance can't affect about but if you can't detect it all the theory could be only theory.
Of course that maybe my system has not enough resolution or my ears could be not good enough to distinguish that capacitance subject. Maybe you can do it but I don't know: could you share your experiernces about?, thank you in advance.

Regards and enjoy the music,
R.

Hi Raul,

Another possibility is that your phono stage is able to handle the ultrasonic resonant peak that Jonathan Carr and Atmasphere referred to, which is sensitive to capacitance, without any audible consequences.

My own experience to this point is just with high output MM and MI cartridges, and therefore is not relevant to the question. The intention of my previous comment was just to call attention to what a couple of distinguished designers had to say on the subject, which from a technical standpoint makes sense to me.

Best regards,

Dear Almarg: Thank's again.

Input the resistance and inductance for your cart, and input capacitance values to see what the resonant frequency is. I think anything above 20 KHz is fine, so capacitance values up to that resonant frequency should be OK.

Yikes! When you are dealing with LOMCs, there is no need to add any capacitance for loading! That has entirely to do with high output *moving Magnet* cartridges, where loading the cartridge does have an effect at audio frequencies.

By adding capacitance to a LOMC, you move the RF (Radio Frequency) resonant frequency *down*, but not likely into the audio band. The inductance of such cartridges is tiny, so the RF resonant frequency is going to be high. In any event, you will have to kill that resonance with a resistor, not a cap. IOW by adding capacitance in effect you have created a bit of a moving target.

Raul is correct, any amount of loading capacitance offered by the phono section is inconsequential at audio frequencies. It can have a huge affect at RF frequencies though; its the ability of your preamp to handle RFI (Radio Frequency Interference) that says how audible the loading is: the more RFI bothers your preamp, the more important you will find the loading.

Thanks Ralph, I'll set the cap on the Steelhead for 0 and have a listen.
