Don't get hung up on the loading thing. 100 ohms from a transformer sounds completely different than 100 ohms from SS step-up. You need to try your desired combination there may be other compatiablility issues at foot that swamp the impedance issue.
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?
