Hi, I am contemplating to replace the stock JJ tube with Genalex Gold Lion for my Preamp ;just wonder what the sonic benefits/upgrade would be. I need your opinions.experiences and suggestion. Thank you
Should be fine. Hey, it's only one tube. If you no like, maybe you can return it. Whatever you do, live with the new tube for a while before making a decision. Welcome to tube rolling. I have scores of tubes that didn't make the grade.
