Objective vs. Placebo relating to system changes


I am continually baffled by the number of people that are convinced that changes to power cords, speaker wires, interconnects, etc. in their systems result is objectively real changes. While I won't go so far as saying that making these changes absolutely doesn't make a difference, I would love to have the resources to challenge people prove it to me and test it with my own ears.

Here's what I would do if time and financial resources were no object (I'm visualizing retired millionaires that are audiophiles).

I would build a listening room where the only components in the listening space were the speakers and the speaker cables coming through opening in the wall where the rest of the system was setup. The idea would be to allow the test subject the opportunity to create their system of choice and then have the opportunity to become very familiar with the system by spending hours listening. Then I would let them know when I was going to start changing different components on them on a very random basis and they should report any changes that they heard so we could link the changes to any potential changes on the other side of the wall.

Here's a short list of things that I'd try:

(1) I would replace the upgraded power cord with the stock unit.
(2) I would install or remove isolation (e.g. Nordost sort kones) devices from a component.
(3) I would replace interconnects with basic quailty products.
(4) I would replace well "broken-in" cables with otherwise identical new ones.

Depending on the results of doing these test slowly over a period of time I would consider swapping out some of the more major components to see how obvious a macro change was if the listener wasn't aware that a change had been made.

I can tell the difference between new and broken in speakers (on ones that I'm familiar with) so I know this break-in is very real and would also not be at all surprised with differences from amplifiers and analog sources being obvious. I'm not as sure about digital sources.

So the question is, what components in your system would you be confident enough to bet, say $1,000, that you could identify that something changes if it was swapped out?

In my system I am sure that I could identify a change in amplification or speakers, but highly doubt that I could do the same with any cables, isolation devices, or digital sources. Maybe I just reduced myself to being a non-audiophile with low-fi gear?

There are many people on the Linn/Naim forums that claim to be able to hear the difference between the two sides of the felt mat. All I can say is that I'm glad my hearing is not as good as theirs. Never assume that because you can't hear something that nobody else can hear it. It's like saying that you can't read fine print so nobody else can. We're all different.
"not necessary for everyone to understand all of the science and engineering that may be involved."

That's the point - there often ISN'T science and engineering, it's mystical nonsense that's justified by saying that "well, you're system can't resolve to hear the difference sniff, sniff", or "well, maybe YOUR ears can't hear, but mine.....".

So much nonsense and BS, particularly when it comes to things like power cords (and I have $500+ ones in my inventory, btw), with people trying to desperately back into an answer like "well, maybe the power actually starts at the component" - c'mon!

It seems that many who so desperately profess to hear the "mind blowing" differences are also the ones that desperately try to debunk double blind testing as they know they'll get outed to the nonsense.
Some folks appear destined to become avid book collectors or model railroaders. Not thst there's anything wrong with that.
Understanding the 'science' behind something doesn't constitute a bar of sorts on which to judge others perceptions since the beauty of that 'science' is that it is disprovable. This has been discussed here at great length before.

If you have any doubts that others can hear a difference and can't experience it firsthand with others, what is the strength of those doubts and just how far are you willing to go to refute them? By setting up a straw man argument?

Not too long ago there was an article on another audio site that went back to one of the first audio double blind challenges that was revealed to be nothing more than an attempt to embarrass audiophiles by a person with an agenda against audiophiles. That person was quickly forgotten but his methods weren't.

All the best,

I'd love an opportunity to be convinced, but my location is not near either of you that offered. My issues relating to sciece are primarily when the science used to market audio equipment is obviously flawed or just unrelated. I don't expect every product to have a scientificly (I can't spell this word today I guess) sound proof, all that I ask is don't lie to me.

An example is the people that sell gold cables stating that they are the best when silver is proven to be superior. The use of gold is mostly like due to the fact that many people associate gold with being the best and assume that it'll cost a lot. If they simply said that the use of gold as a conductor provided a color to the sound that they preferred to silver or copper, then I wouldn't necessarily call BS on them.

My original question was intended to set a stage "where all other things are equal" as the foundation of the discussion and then find out what changes in the system people are 100% confident people could identify. This goes to the heart of the discussion about the value (i.e. cost vs. improvement vs. I swap things for fun) of upgrading and/or changing equipment.

In my case, I'm perfectly happy with the sound of my system, but purchased a tube integrated (I was given most of the money as a gift) because I just wanted to experience something different than what I have. I won't even be surprised if I prefer the sound of my solid state gear, but only time will tell.

I'm not against changing for the sake of changing, but that should be the reason and not I'm spending an additional $10,000 on an interconnect when I couldn't tell if you swapped it out or not if you didn't tell me.

When I had Nordost Sort Kones demonstrated under a CD player on a system with speakers in the middle of the Focal Utopia line and a Pathos amplifier, I was convinced that I could hear a difference, but was equally convinced that I would never be able to tell if they were in or out if I just walked in and wasn't doing an A/B comparison. And, I still ended up with a pair because curiosity got the better of me.

My first question to the salesman was if they made more of a difference on cheap CD player compared to the $10,000 ones and was suprised that they seemed to work equally. My next question was why a company selling a $10,000 CD player wouldn't either incorporate a similar design or just work out a deal with Nordost to include them with the purchase.
