By reading these posts and a zillion other where DBT, ABX testing, etc etc. are challenged as far as the results obtained, there is a contradictory explanation given by those who firmly states that DBT is not enough to conclude whether there are or aren't differences in perceived sound, and it goes more or less like this:
"we need a long term relationship (monthes sometimes!) with the (whatever gear) to find out about the differences, and a single DBT is too little time to do it"
Well, this is the first part, but then we hear or read:
"I heard last night the brand new "XXY" high end CDP, and it was absolutely a no brainer to conclude that it was far better than the "ZZZ" we compared it with"! Or "What a difference those cables made on my system! I could immediatly hear the difference with my old cables!"
So, those whom states that we need to live with our cables or those high end snake oil gadgets for about 30 days before we can really appreciate what it does, are usually the same whom states that "it was immediatly perceived the difference"....
See? the story is almost always the same...
Why then, people that swear having heard differences, and being able to identify wich rig or even cables are being used, when offered to prove it they either pass or criticize the BT?
I was myself told "you have no musical education, thus, you are not qualified to hear subtle differences". Allright, the bashing we all know. BUT, I wonder, why I was a honorable member of the golden ear club when I was in the firm belief that I heard differences? Why was I a qualified tester to choose wich brand of cables was the appropiate for a given set up only until yesterday and today I have no ears?
"Oh, maybe you never were a GE" really? Strawman arguments.
Worse yet, somebody agrees to it, and finds out how difficult it is to even perceive any difference (much less identify the source) in between, fx, cdp's.
Mockery from the GE gang is to be expected. "he was under pressure", "the chosen enviroment was wrong", "the music choice was not right", "you had too many cocktails before testing"...and so on.
This is why DBT is such a hot issue all over. Because the minute someone says "I have tested this and couldn't hear ANY difference at all", the other side comes in a bunch saying "you and your uneducated ears"...and I'm sure I'm not the only one here whom heard this.
ps: I love high end gear, don't get me wrong, and I love thick and bright cables, massive or designer CDPs, and I admit, I love owning the best (who doesn't?) out there, but, I don
