Phono Preamp recommendation for VPI Prime
I just purchased the Prime. Currently have a ortofon 2m black cartridge but envision going to a MC cartridge. Current components are a Mac ma-6600, Revel F-30 speakers. Do I go tube or SS. Some of the ones I have started to research are Lehman Decade, Pass Xp-15, Manley Chinook. Any help sorting through this maze is appreciated.
