As I wrote, it's 'trusting ones' ears' more than a particular regime.
By 'trusting ones' ears' I mean making sure that what one hears is the actual sound, not prior expectations, nor any other bias.
Furthermore, no one else can possibly hear what I hear. Others can hear the same sonic signature of various pieces of gear as I do – but not what I hear. Actually, I know some others who observe the very same sonic signature that I do.
This is definitely a possibility.
There is a possibility that I'm fooling myself.
There is a possibility that I'm deliberately lying.
It looks to me unwise neither to believe me nor to disbelieve me only because of I said so.
On the same token, those who are convinced that I fell pray to placebo effect are unwise, because of they have no way of knowing the facts of the matter. They are only guessing, however, they confuse their guesses with facts.
What you mean and what you say are not the same. You have demonstrated nothing which would indicate that you eliminated expectations nor other biases. You flat out refuse to provide any details.
I've never stated that.
Had I thought so, I would never have provided you any information in support of your assertions.
You've provided no facts.

I'm not clear about what you mean me refusing. I refuse what?
1. I didn't say I don't know the technical arguments, I said I have no interest in discussing in this thread those technical arguments.
2. AFAIK, there is no solid explanation of why power plugs of the same manufacturer, having different coatings, have different sonic signature. I looked at you gallery and found no explanation for that. If you have an explanation, I'd be glad to hear it. Please note, I'm talking about power plugs, not RCA or XLR plugs.
My explanation is that the rest of the audio chain is that bad that even the change of power plug's coating makes an audible difference.
I strongly suspect you have more problems than just audio.
May I suggest that we just do a power cable shoot out, the looser in this thread gets to go naked in the streets with an LP to cover up wherever most necessary.😀
Joshua_G,
here is a thought for you. Could it depend upon the mains supply?
Lets make an assumption: Could the construction of the cable in some way filter the supply?
Ie if the supply was " clean" then might the difference not be the same?
So the cable should not "Add" anything correct?
The assumption is that RF etc cannot pass through a Tx. 🙂
Of course this is interesting based upon harmonic distortion of the mains supply.
So could cable cancelation of (call it what you will) mains distortion be an issue.
People will argue that the mains supply is "converted to DC" within equipment before use and so its not an issue. Then again any contact area if "it corrodes" will cause interference via arcing linked to current draw.
However this superimposed "noise" should have no effect. Then again..what could a cable do that a filter can't...
On the other hand how would the magnetic field around a cable vary based upon construction assuming that equal and opposite fields exist on each supply cable.
Then again would this be dependant on which end of a Tx primary was connected to which cable (start or finish of the primary winding). And or Tx type.
The argument will always be, well it has no effect on my computer so why all the hype for audio.

I have demonstrated it to myself.
I see no point in trying to demonstrate it to others, since it's a very long story of how, over the years, I came to know that I can trust my ears.
Furthermore, those who are convinced now that I fell prey to the placebo effect will continue to be convinced about it, no matter what I may write. I did it before and came to realize that this is the way things are. When people operate out of beliefs, no logical arguments are going to move them from their beliefs.
On top of that, I have no wish to move anyone from whatever beliefs one may have.
Thank you.
I spoke in general terms, covering all possibilities, in the view of all people. I didn't referred to you in writing that possibility, I didn't think you viewed it this way.
Indeed, I provided no facts, I shared my experience.
There are two basic possible reactions in such a case (where there is no evidence):
1. "Without evidence, I cannot know if what you shared are facts, or non-facts, hence, there is nothing I can do with it".
2. "What you say is impossible ([in my mind]), therefore you must be under the placebo effect, or similar illusion".
The first above reaction is unbiased (and to my view, a wise one).
The second reaction is born of inner beliefs about certain technical aspects.
Examine the analysis of the IC return current path which includes the power ground. The return for the low level signal will be split among the various paths dependent on the frequency of the audio signal
The ground loop resistance is very low. Modifications to something as small as the insertion contact resistance of the grounding conductors will alter how the signal ground returns.
The bottom line is, it's not the cordage that is causing the problem, it's the equipment design.

I use my own inside equipment..🙂..my experience is that the longer the cable the "better" it would seem to be.
However that's just my assumption.
The comments will tend to be, if the PSU is "solid" you won't hear a difference.
Then its back to is the detail hidden or is the PSU badly designed and so it goes on.🙂

Your assumption does make sense. It may be so, at least in part – and it may not be so.
However the possible filtering of the power cords doesn't explain why different power plugs have different sonic signature – when none of those plugs contains any filter. Furthermore, it doesn't explain why different power plugs, from the same manufacturer, with the exact same construction – but with different coatings – have different sonic signature.
Its got to be,
Either contact resistance (cable to plug /plug to socket) linked to conductor types or insulation type.
However to hear this would create the question is it mains noise or superimposed on the ground/earth which as we know is not clean.

You are referring to IC, which I believe are Interconnect cables, while I referred to power plugs.
Possibly it is so.
Even if it is so, I have commercial amplifiers (expansive ones) which I cannot change their design. Therefore I use whatever means are beneficial to the SQ of my system, be it isolation transformers, cords, cables, and so on.
This is the logical conclusion, however I'm not sure if it's the actual and full explanation, or not.
BTW, the power plugs with different coatings have the same insulation and are attached to the same power cables.
Its interesting,
If you make a DC supply and double regulate it to two lower levels you can create a very low noise supply when looked at with a scope. Then connect the Earth/Ground and see the amount of noise that is now superimposed on the supply even after all the regulation.
However safety has a part to play and so the noise is on the Earth of supply.😀
Of course this creates the question can we clean the Earth/Gnd before it reaches the equipment AND not effect the safety for disconnection of supply under fault conditions.
Just a few thoughts.

I'm not sure if the noise, which part of it is RFI, can be seen on a scope.
On a first glance, I don't see how we can clean the Earth/Gnd without violating the safety rules.
If anyone may have an idea, I'd be glad to see – and possibly try.
BTW, I have 4 isolation transformers, feeding my sound system. All of them are E-I core, each has balanced secondary and simple RFI filter before the primary.
