You are getting some excellent suggestions here. Herron is very well respected, and agreed on Shindo from experience. I believe ILS in NY has a Monbrison for sale. It is a used trade in on their website. If you are looking for a line stage only, a CJ Premier 16/2 just came up here the other day. That's a hell of a preamp as well. I had the 16/1, and always loved it.
