Why do intelligent people deny audio differences?


In my years of audiophilia I have crossed swords with my brother many times regarding that which is real, and not real, in terms of differeces heard and imagined.
He holds a Masters Degree in Education, self taught himself regarding computers, enough to become the MIS Director for a school system, and early in life actually self taught himself to arrange music, from existing compositions, yet he denys that any differece exists in the 'sound' of cables--to clarify, he denies that anyone can hear a difference in an ABX comparison.
Recently I mentioned that I was considering buying a new Lexicon, when a friend told me about the Exemplar, a tube modified Dennon CD player of the highest repute, video wise, which is arguably one of the finest sounding players around.
When I told him of this, here was his response:
"Happily I have never heard a CD player with "grainy sound" and, you know me, I would never buy anything that I felt might be potentially degraded by or at least made unnecessarily complex and unreliable by adding tubes."

Here is the rub, when cd players frist came out, I owned a store, and was a vinyl devotee, as that's all there was, and he saw digital as the panacea for great change; "It is perfect, it's simply a perfect transfer, ones and zero's there is no margin for error," or words to that effect.
When I heard the first digital, I was appalled by its sterility and what "I" call 'grainy' sound. Think of the difference in cd now versus circa 1984. He, as you can read above resists the notion that this is a possibility.
We are at constant loggerheads as to what is real and imagined, regarding audio, with him on the 'if it hasn't been measured, there's no difference', side of the equation.
Of course I exaggerate, but just the other day he said, and this is virtually a quote, "Amplifiers above about a thousand dollars don't have ANY qualitative sound differences." Of course at the time I had Halcro sitting in my living room and was properly offended and indignant.
Sibling rivalry? That is the obvious here, but this really 'rubs my rhubarb', as Jack Nicholson said in Batman.
Unless I am delusional, there are gargantual differences, good and bad, in audio gear. Yet he steadfastly sticks to his 'touch it, taste it, feel it' dogma.
Am I losing it or is he just hard headed, (more than me)?
What, other than, "I only buy it for myself," is the answer to people like this? (OR maybe US, me and you other audio sickies out there who spend thousands on minute differences?
Let's hear both sides, and let the mud slinging begin!

It has also been proven that people imagine differences that are not really
there at all. John Dunlavy used to do an experiment where he would gather
audiophiles in his lab, position a technician behind a set of speakers, change
speaker cables and the audiophiles would claim to hear large differences --
but the trick was -- the cables were never changed. Now, show me an
audiophile who is open to the idea that there is a very real possibility that the
differences he/she hears is due to his/her imagination and I'll show you an
audiophile who is REALLY open minded. There is more than enough irony in
listening to audiophiles who think they are immune to such imaginary effects
calling others closed minded. Unless you can prove that you aren't imagining
the differences you are claiming to hear or that the differences are audible to
your brother, there is nothing here but a he said/she said type of debate.
There is a very real possibility that some of these alleged differences are like
the emporer's new clothes. Without proof of the existence of these alleged
differences, there's no proof that there are any clothes to see. So, in absence
of that proof, there's no justification for smugness on anyone's part.
Anecdotal testimony with regard to these alleged differences wouldn't hold
up in any scientific debate. So, what do you do when you're debating sounds
that haven't even been proven to exist -- and no anecdotal testimony is not
accepted as *PROOF*. So many of these alleged differences disappear under
double-blind testing that, IMO, a little humility is in order. Show me the
humble audiophile who is open to the possibility that he/she is affected by
peer group pressure and his/her imagination and you win a trip to Bermuda!
But, if YOU are satisfied that you hear these things, be happy. If others --
like your brother -- are cynical, you've got no magic bullet to end the debate.
Further, just as people can imagine hearing differences because they think
they are supposed to -- it stands to reason that people can fail to hear
differences because they think they are not supposed to. Also stands to
reason that one must think any differences, if they do in fact exist, are worth
hearing in order to hear them. These are just some of the reasons these
types of debates rage on. And, why the correct response, IMO, to either
position is just a bemused, "oh you!" But -- that's just my
opinion.
Great post! I love it. Does your brother have anything to say about speaker breakin? Book smarts mean nothing. My IQ is over 130. So what!

Sometimes it takes 20 or 30 minutes of loud music to what the amp. is really doing. Maybe he is tone deaf.

It reminds me of the old days, when kids would come into the shop saying that they got an XYZ amplifier for $100, and it sounds as good as any other amp because it had only .00000001% distortion, and no other amp could possibly sound better than that.

Some things never change.
Lugnut nailed it. Academia Nervosa.

My brother maintains an information network at a large university, yet:

My brother believes the US government has deceased alien corpses locked away in a meat locker. He also believes everything Oliver Stone sends his way.

Sucker!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
