"For those who find this whole exercise/endeavor foolish and a waste of time, OK I understand. Just ignore and don’t participate."
I don’t think that a differing opinion should disqualify a member from expressing same. As I said, I have listened to quite a few of these videos out of curiosity, and still do, but I just don’t believe that it’s a medium suitable for judging subtle differences in grounding devices, tube types etc.
I remember how jaysaudiolab used to do it every day when he was on audiogon. Anyway, I certainly don’t want to cause hard feelings about it with you or anyone else.
