Hello Tekerman, and welcome to thecarversite.com. We're glad you're hear. There is a lot of information here, much technical know how, and a pretty good bunch of folks that are happy to help.
You won't go wrong with either of those preamps. I have a BillD modified C-1 and a Bonzoro modded 4000t. Either one is the right choice.
Once you get to Novice status, please consider uploading some pics of your gear in the Members Systems area. We all like pics of all kinds of audio gear.
In the meantime, kick your shoes off, turn up the music, and welcome aboard.
