The idea of the Microphone-Parts Mod is to get a Neumann U87 like sound. I had the opportunity to buy a second C1 and compare them to my modded C1. The modded was a revision 2 and the original one is a revision 3, so they chanted some things in the preamp. I don't think that has a huge impact on the sonic footprint, it improved more the sensitivity and the noise figures.
