One of the reasons I started experimenting with moving magnet and moving iron cartridges is that they seem less fiddly with regards to impedance loading. I was having hell of a time trying to find proper impedance load for moving coil carts. I even purchased Lehmann Audio Decade phono preamp because it has the ability to let users custom load the impedance. Alas, I did not realize when I was buying it (online) that I would have to unscrew the body and open it up to be able to access the slots for the resistors. Too cumbersome and inconvenient. So I kind of gave up on that.
With Empire and Grace, at least I don't need to worry about that issue.
But since I'm using Dynaco PAS-4 tube phono stage, I have no idea how would I modify the inductance? Or even if that modification is needed?
