Clever Little Clock - high-end audio insanity?

Albert,
You want some fun? How about trying the CLC "Clever Little Carp" You mount it on the wall and everytime you walk by it sings Patricia Barber songs - thereby recalibrating your ears prior to a listening session. I would suggest you introduce to your listening group prior to your normal Tuesday night sessions.

Listen Slipknot, Patricia Barber songs "Carp" on me enough, even without the "Billy Bass' Replica (or is that Trout Mask Replica?) hanging on the wall.

Joeylawn36111, Audioari1, and Albert, I could not agree more. This is why I suggested that such present or not present tests may not validly assess whether the CLC is working or not.

Zaikesman, you are assuming that no one can hear a difference, but I am assuming that some can hear a difference. Certainly, some do say they hear a difference. With a small sample where some hear a difference, as I see it, you will not be able to dismiss the issue of whether your sample is unusual but comes from a population that cannot hear a difference. With a larger sample again where some hear a difference, it will be very improbable that the population cannot hear a difference. Statistical significance would make it more difficult to support your position. I am sorry if these ideas are difficult to convey, but they are the basis statistical significance and dealing with type one errors.

Given what I say above, a small sample with some hearing a difference could be dismissed as sampling error. A large sample would, however, lead to the conclusion that people in general can hear a difference.

Remember also that you think that there is no difference with the CLC present or absent, but you are only testing whether people can hear a difference. Even if they don't hear a difference, there may be one, or if they do hear a difference, there may be none. Unlike a coin where all would agree on heads and tails, this probably would not be the case in what you propose.

Overall, again I would state that your proposed tests do not resolve the issue.

Hey, I'm not taking sides here, just agreeing about long term listening.

Zaikes is suspicious about this thing working and so am I, but I have not tried it. Because of that, I've avoided comments except for fun remarks with the rest of you guys.

The CLC guy has probably sold about 200 clocks over this thread if it has a fraction the power the "Home Despot" (Lenco Turntable) thread.

Hell man, their fighting over them at Ebay (the Lenco, not the clock :^).

Again, I don't disagree with the point everybody makes about auditioning and testing. But I still say an experience like the one Audioari1 relates about the $10K preamp vs. the $200 one -- if true and valid (meaning if this actually happened, and if the test was done well) -- is a valuable reminder to any audiophile about not just the limitations of A/B testing (which I think audiophiles sometime tend to overblow, while ignoring the equally significant foibles of long-term auditioning), but also the quite real limitations of what we're actually doing in high end audio.

But I'm getting a little off the track here. There is most definitely a way to test the CLC that doesn't raise the possibility of criticisms like you guys are mentioning (and I already thumbnailed it somewhere here before). All you would need are, say, three outwardly-identical clocks: One would be an actual CLC, with its supposed "proprietary technology" and "special" batteries, while the other two would be the same model of clock, unmodified except for having identical stickers placed on their fronts as the CLC, and with "regular" (but same brand) batteries. The test administrator would need to have some kind of identifying mark to reference the CLC; I'd suggest maybe tiny pieces of tape placed inside the battery compartments of the two stock clocks only.

Then simply leave all three clocks with an audiophile who maintains he can hear a positive effect from the CLC, to audition however he pleases, at his leisure (with the understanding of course that he wouldn't try to open up the clocks or otherwise try figure out which is which through non-auditory means, and the proviso that he removes the two clocks not currently being auditioned from the listening environment in accordance with Machina Dynamica's guidelines). When he's finished and indicated his preference, the administrator would remove the three clocks and note which one he chose, then bring them back mixed-up and do the same thing over again (without, of course, letting the subject know the running results while the test is still in progress).

If, after maybe 10 times around with this routine, the subject couldn't correctly identify the CLC significantly more frequently than 1/3 of the time, I don't think that audiophile could argue about its lack of audible effect. And if he could identify it reliably (and hadn't cheated), no one could argue that it's probably really doing something after all. (I think the single best candidate to run this test with would be Mr. Kait, were it not for the fact that he would have an infinite incentive to cheat, and the means to easily do so!)

I'm not advocating going through this kind of crap for every choice an audiophile makes (I've stated above why the CLC [and "Intelligent Chip"] deserve a higher level of skeptical scrutiny), I'm just saying that in principle it's hard to criticize or dismiss this test (or at least, in the case of negative results only, as it could apply to that one listener). And yes, I've stipulated before that this whole debate is likely nothing but great for Mr. Kait's business -- while it lasts (meaning the business, and the debate! ;^)
