Wish I had my Infinity FET preamp back. My bad trading it for a Bedini 66DE preamp, removed in short order. Didn't know anything back then. Never will decide based on a quick swap and listen with time constraints... need time to assess gear, at least a few days.
Is there any one piece of vintage gear you most wished you owned?
Assuming vintage interests you, what one piece of vintage equipment would you most like to own?
