Cartridge Loading...

My phono preamplifier has 65 dB of gain and a fixed 100 Ohm impedance load. I would like to use an MC cartridge that has a 0.5 mV output (which should be fine with 65 dB gain), but which requires an impedance load of greater than 500 Ohms.

I've heard somwehere that it is possible to have a tonearm cable custom built with internal componentry to create an impedance load of predetermined value, for a case such as this. Is that true, and if so do you know who can produce
one of these?

Why not tell us what you have, so we can help with specifics.

The numbers read funny thoug: very hard to imagine a 0.5mV output MC has impedance requirement of 500 ohm (i.e. the number of coil turns is high...).
