In my experience, it's been always like this: If one truly believes there will be a difference, there will be a difference. Vice versa.
People call bs due to placebo effect, but as I always say, if the placebo actually cured the headache, then the sugar pill actually worked as a painkiller.
In the end, I guess it's up to the person to decide. As a cable believer myself, and an OCC fan, I would still not pass up Q. It's really one of a kind.
I've heard this story 10000 times too & I agree. I trust my ears more than I trust stories.... I am 100% sure that there are differences. If there weren't I wouldn't buy a cable just for the looks...or the smell

)
I am not saying this is not true to some audiophiles....but this excuse is used too much...
I had times I believed it to be better because of the price before listening to it, bought it, and afterwards disregarding the more expensive cable and remained with the stock. (this happened many times)
Also had a period that I wasn't attracted to my sound system no longer, and then realized it was a coax cable that made the sound very slow...(for me), changed it and then all was ok again.
I have said this a few times now. The problem is that our audio memory if not trained (or have it naturally) is very low, as we are visual animals that rely on vision, not hearing.
The question is this :
How well can you distinguish subtle differences in rhythm?
The above test is good for audio memory and also for hearing. If you have a low score and have problems in telling 2 different rhythms apart, I think it would be even harder to distinguish the differences in sounds with same rhythm but with other changes in details, soundstage, transients, etc
There is also a question of hearing capabilities and age (I have done an audio-gram recently and I have close to perfect hearing...)
I find it funny when somebody doesn't see something...and then he wants to believe that all in the world should be like him and nobody else sees that, and all who see are wrong because..HE cannot. ( it is more comforting to believe that, I guess )
P.S. Last week I did a blind test with a friend (coax cables, digital, not even analog) and I recognized the cables...easily ( even in digital you can see the difference. I agree to the fact that you shouldn't but that only happens with digital done right and I have only listened to one dac that did that)
