Best loading for Monster Cable Sigma Genesis 2000

Dear Smcclure: The recomended load impedance is what Bob already told you.
Andrew G. Benjamin ( TAS reviewer ) report that at 47K he had a very good cartridge performance.
Regards and always enjoy the music.

Curious if anyone has compared these cartridges back to back, since they are made by the same person? Are the ZYX's an evolution of the Monster cartridges, or totally different.

I just put my SG2000 back on after a retipping, and am loving the sound..
