Joe: The room would explain it if many people did not listen in the near field. I don't ordinarily, but do when I am testing new stuff to buy at home. On the otherside of the coin I have also experienced "burn out" on older tube stuff that I have kept for over ten years. It was, I thought, well maintained. I don't know how revealing the systems were on a whole, but they weren't a match for my ears, that's for sure. If you still have the Silverline's that you mentioned in another thread, I am suprised that you do not hear a difference in new cables. Try reversing a pair of IC's sometime when it's quiet and you have the time to listen. I did this by accident once with a pair of silver IC's and was very upset with the results until I figured out what happened, which only took a few mintes of backtracking.
