Dinster, That list of resistive loading options for your Audia Flight is indeed very odd. Perhaps there is a built in SUT for MC. Sometimes the stated value of the load is tricky to interpret when there is a SUT and if the load resistor is installed in front of or after the SUT. BUT, I really cannot imagine loading any cartridge at less than 30 ohms, net. And why one would need a choice of both 90 and 100 ohms, not to mention 7, 9, and 10 ohms, is also a puzzle. Something is fishy.
I just Googled Fremer's review of the Audia Flight from 2009. He wrote the following as regards cartridge loading, "The jumper system offers 16 logically chosen values between 60 ohms and 47k ohms, which was more than enough for me."
