paperweight- Who was it that admitted they don't know what they are talking about? Certainly NOT ME! I've probably forgotten more about audio gear, than you will ever know. I've been building, modding and repairing pro and home equipment for over thirty years(the better part of that time: professionally). NOR did I say, "the manufacturer says." What is TRULY, "ridiculous", is your lack of comprehension skills. My reason for leaving SS gear on, is the sound quality(which is everything to me), rather than longevity. Everything simply sounds better that way. If you can't hear any difference, or are simply satisfied with your mediocrity; What do I care? Like I said, "HAPPY LISTENING!"
