Magic Diamond vs Airtight PC1?

In my quest for a new cartridge I seem to be narrowing my choice down to a Magic Diamond vs Airtight PC1. I have not been able to hear either of these so I am looking for any insight anyone can provide. I will be using the cartridge on a VPI TNT IV with an Eminent Technology 2.4 tone arm with the high pressure manifold. I am running dual mono with two Krell KPA Phono preamps. Thank you for any input.
