Tube Microphone Pre-amp Inputs

[makinrose]

I've been thinking about building some microphone pre-amps for recording purposes. Since the microphones I'm using are Lo-Z I was looking at matching transformers and at the cathode input circuit from TUT-2.  I've built pre-amps with matching transformers but have not had any experience with a cathode input circuit on a mic pre-amp before.  Are there advantages or disadvantages to that circuit versus a transformer?  Do they sound different?  Thanks guys!
