What's up with picofarads?


What sonic differences generally occur by changing the MM picofarad (pF) settings of a phono section. My Pass Aleph Ono allows "none," 100pF, 220pF or 330pF and allows any combination of the three totalling 650 pF (plus 2 DIY custom settings). I really can't detect any difference from one to the other. I'm using a Sumiko SHO cartridge on the MM setting.

Many MC's are affected by the capacitance that they load into. The fact that your cartridge doesn't seem to be "bothered" by any of the settings tells me that it is probably less sensitive to capacive loading. You might want to experiment with the resistance of the load though as this surely WILL alter frequency response. Sean
