I have an Ortofon OM20 that I'm using. Since I am pleased with the tonal accuracy and tracking of the cartridge unlike any other, I wish to work with it. What I don't like is it's rising upper midrange and treble response along with somewhat lean bass. I've read about people changing the capacitance of their phono preamps to effectively equalize the sound of the cartridge. How is this done? Do you add capacitors in series with the phono leads? My phono preamp input sensitivity impedance is 2.5mV/47K ohm, 125pF. What values would I use or how would I alter things to roll off the highs and boost the bass of the Orotofon OM20?
