I had the C1 Capacitor upgrade done to a Premier 140 amp. Maybe I'm not sensitive to it but I thought it sounded better than the unmodified original right out of the box. CJ did burn it in for a few days prior to shipping it back to me. After about 300 hours it stabilized with further improvements to clarity, better extension at the frequency extremes and a more fully fleshed out sound stage.
