Hay guys

I started reading this thread and very quickly became confused

I have a Ortofon 2M Red and I'm looking to try my hands at a MM jfet pre, which design here is best to go with?

I believe Mad's is the one that is suitable?

Edit:Guess I'll have to back track through the thread to get a clearer understanding...
