To ICYR Anus: Blind testing introduces tension variables, such that even obvious differences become less obvious. Also, I firmly believe that you need visual stimuli and room orientation, for the "aural memory" to function properly. When you are in a blackened room, or wear a blindfold, all sorts of things can happen as your brain perceives the sound. YOU AREN'T USED TO DOING THIS SORT OF THING, UNLESS YOU ARE WITHOUT SIGHT TO BEGIN WITH. For instance, nobody denies that it enhances the enjoyment listening to do so in a darkened room. It's easier to "see" with your ears that way, and forget that you aren't at the concert hall. BUT WHAT IF YOUR HEAD SLOWLY SCEWS OFF IN ONE DIRECTION, AND YOU DON'T KNOW IT? SUDDENLY THE IMAGE CAN BE SLIGHTLY LOPSIDED, AND YOU DON'T KNOW WHY (or even consciously realize that it actually is lopsided)...since you cannot orient to the room/speakers. And there in lies the problem. Personally, I have not been able to listen with the lights off, without getting lulled into such a trance-like state, that it forces/compels me to CEASE ANALYTICAL THOUGHT COMPLETELY...and I just enjoy the music in a very "pure" way. My mind starts involuntarily imagining myself as floating, or even swimming around in the air, amongst the musicians/performers. The point is, I could still be hearing things like cable differences, but my aural memory forgets them, or else forgets to pay attention, and I don't even realize it. With the lights on, and myself changing the cables, I pay attention to every detail. Then I switch cables back and forth several times (I'm not a firm believer in settling times of cables, so long as they've all been up and running in the very recent past). I confess that if I (as many do here) forced myself to listen to a cable for months at a time, without changing it, I would get used to it's sound, and definitely could not remember how it's character affected music in a different way, from the previous one months before. I don't understand how anyone could make cable choices that way. In any case, if I can change cables back and forth, play the same piece of music, then move to a different piece of music...and I STILL hear the different signature as cables are changed, WHY SHOULD I QUESTION MY OWN HEARING, WHEN I JUST REPEATED THE TEST WITH DIFFERENT MUSIC, BUT HEARD THE SIGNATURE OF THE CABLE EXHIBIT EXACTLY THE SAME SORT OF EFFECT ON THE MUSIC? This has always been the case for me, when I compare any type of cable, and frankly, I have no reason to doubt what I am hearing...It isn't my fault that others might not trust their hearing, and want to take a "court of law" mentality, where everything MUST be controlled (so that the person who is listening is somehow out of control). WHY IS THAT MORE VALID THAN MY WAY? I guess it's like Parliamentary procedure, or something. Some people just can't make decisions for themselves, unless they get permission to do so from a group of people. I'm kind of a maverick individualist, I guess, and I like to do things my way...epsecially when I've never had a valid reason to doubt my own hearing. And yet, I DO have plenty of reason to doubt the hearing acuity of those a generation older than me...
