Sorry I didn't respond to you above Tgun5, we must have been composing at the same time. I don't want to rehash everything that has been written, but most of what you say is confirmation of what I see as the problems inherent in your assumptions:
"I surmised that if there was going to be a difference at all, it would probably be because of the clock, not some modification to a clock"
"Trained audiophiles know what to listen for and how to trust what there are hearing to get the results"
"I am also convinced that I have been blessed with the ability to discern differences in sound, their overall effect on the system, and the proper approach to improving the sound"
I do find it just a little intriguing that once again, I seemed to have "hooked up", so to speak, in one of these threads with an audiophile who unshakably believes in his own infallible ability to detect changes in sound caused by something he admits couldn't have any possible effect -- this despite not taking measures to ensure his results aren't spurious -- and that such a person also makes a point of correlating their position in this regard with their religious belief. As you've surmised, and as I told Wellfed offline, it is indeed true that I don't share any beliefs of that type, for whatever that's worth. Although this sample size is certainly too small to judge from (ha! :-), it does make one wonder about the possible connection between faith, or the ability or willingness to believe, and the types of audiophiles we are.
Anyway, the main thing I'm trying to get across here is that "open-mindedness" doesn't just mean being willing to contemplate anything that's suggested by someone -- I could suggest that bringing a rubber ducky into the listening room makes the sound better. It also means a willingness to question oneself. In your threadhead, you expressed what sounded like a sincere desire to test the results you say you found so suprising. I'm simply pointing out, if you care, that you haven't actually accomplished that yet, and why.
I can sympathize that repetitious A/B tests and especially blind tests are not very enjoyable as an entertainment activity, and are a pain in the neck to perform. I think it's great that you're now willing to attempt them if you can, and in fact I think that willingness is more important than if you ever actually do. It's not my desire to "make" you give up your clock by proving you "wrong" -- frankly, I'd rather you acknowledge the human susceptability of yourself and your other listeners, but then go right on enjoying whatever it is you think the clock is doing for you. If you really do perform the number of blind trials necessary to get a reliable answer, there's no doubt you'll discover that you and your friend can't identify the clock's presence unsighted, and though you'll have learned something valuable (not about the clock, but about listening and about yourself), you'll also be at least a little disappointed I'm sure, and it's not my aim to be the cause of that.
At least we agree on the impact of your adventures regarding the Geoffkaits of the world (assuming, of course, that this whole thing isn't actually a kind of 'reverse troll' on your part, which would *make* you one of the Geoffkaits of the world ;^). I pointed out his apparent dilemma several posts ago, but so far silence...
PS -- BTW, I didn't say I was an especially *good* musician ;^)
