Cartridge impedance loading question


Hi folks. I have a Shelter 501 Mk 11 cartridge going into a Lehmann Black Cube phono pre. The Shelter's impedance is 12 ohms. The recommended load impedance in the Shelter specs is ambiguous…

Other than a user retrofittable option the Lehmann moving coil options are 80, 100, 470 & 47k ohms. What would you be using?

Thanks!

I'd start with the 100 ohm setting, but the settings are
pretty easy to switch. Try them all and see what sounds
better.
Pretty easy to switch for SOME of us. I have to open the unit and remove and replace resistors... Don't tell me I only have to do it once when setting up the cartridge...I've already done it once, but wonder if a different value might be better.... The joy...
Stringreen...the OP's Lehmann has dip switches inside. He could put the cover back on, but leave the screws off until he found the right setting.

I think even you could handle that? :-)
