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!

*The larger you make an air coil, the lower its inductance.*

In this case larger means more turns - higher inductance.

*The noise that a phono section has is usually not a function of loading. There are a lot of factors that have to do with noise- it is an immense topic.*

Okay. By the same token loading preference is not always a function of noise, as you contend.
Lew,
Congratulations on the new cart.
You might find that dynamics and stage get larger with a higher value load, and focus more precise with a lower value.

Sloppy bass would suggest a lower load. It might take some experimentation.

Thanks, Fleib. Which is why I next intend to try the third alternative readily available to me, the way I have set up my MP1… 1000R, in hopes that it will provide the best tonal balance. But 47K is soooo good!

Of course, now I want to re-visit all my other LOMC cartridges to see what if anything I've been missing, to include Koetsu Urushi and Ortofon MC7500. Ironically, I purchased the MC7500 from Raul early on in the course of his MM thread. Then Raul always said his fave LOMC was the MC2000.
Hi Lewm,

I am a bit surprised at your preference of 47K for the MC 2000. I own two of them and find 47K a bit bright in my system. I much prefer 100 ohm. Do you know what the Nom. Capacitance (pF/ft) is with your phono cables?

^^ this is how prevalent the cartridge loading mythology is!

Here is an explanation of why this cartridge may not have sounded bright in Lew's system:
