In this example it's not necessary to interleave terms that can perfectly exist individually.
-polluted is not the same as altered ; in this case if we hypothetically think of altered, it doesn't have to be polluted.
-electrically I think of no reason why RN60 resistors or 5532 opamps might pollute or alter, at least significantly an electrical signal.
-finally this should not be considered as a proof that RN60 resistors or 5532 opamps could not bring an audible influence within a domestic audio system.

I don't care if they do or don't believe it. I learnt something about human perception and specifically "my" perception. Some people aren't up to a challenge like this. It's tough to throw away long held beliefs.
I assert I cannot hear differences between competently designed electronics. Those who assert they can have the burden of proof, not me.

My beliefs changed through self education and rigorous testing. Many here are unwilling to challenge their beliefs.
No offense but why are you here at DIYAUDIO then?How can audio be a hobby for you if you can't hear a difference between components,whats the point?
Blind listening tests are the fast track to uniform mediocrity in audio products. Being able to guess what is behind door #1 or door #2 is irrelevant, and better left to game shows.
The best way to remove/reduce personal bias is to have a constant, a control, and make judgements relative to it. This will also account for changes in our hearing, and other variables.
He didn't claim he doesn't hear differences at all, but only between equipment with particular technical conditions, as far as I understood.
That is blind listening testing! You're contradicting yourself! The blind part just ensures the judgements aren't cheats.
A blind test removes the chance to see the equipment being tested, nothing more.
A sighted test inserts another variable, which is the chance to be biased by the equipment visual identification.
-A failed blind test is not absolute proof of inaudibility.
-A successful sighted test is not absolute proof of audibility.
Neither is absolute proof of something, as there are many other variables to begin with that influence the result and most are psychological.

How did a question regarding sourcing of resistors turn into (yet another) discussion of audibility 😕
Most often it starts when there's a subjective claim of audibility, then someone skeptical about it suggests otherwise.
In this case our member Merlin shared his opinion on RN60Ds being better sounding to his ears. And it all started.

There is so much more to electronics engineering than randomly choosing boutique parts. I worked my entire career in the aerospace industry. I know when these parts pay for themselves.
If needlessly spending more money on electronics components makes this hobby meaningful for you then that's perfectly ok. Just don't kid yourself into thinking you can hear it when all biases are removed.
I was referring to your statement above, not about an individual part.If it all sounds the same what are your goals with DIYAUDIO.
Really just curious.
Don't get me wrong, I love exploring the state of the art in engineering, specifically audio. 40 year old resistors don't define that state of the art.
I'm also under no illusion that I can hear many of the differences that I am able to reliably measure.

Exactly right.
I only just noticed this is an old thread that has been dragged back to life.
No it is not blind at all. I am fully aware of "which is which". I am listening for changes, and correlating it with measurements, not making absolute judgements about "which do I like best" or "which one sounds better". That only comes in near the end of the design/tweaking process.
The control only changes when there is absolutely no doubt of its merit.
It's like walking up a ladder, establishing firm footing at every step, instead of trying to jump from rung to rung.
So how do you remove the influence of expectation bias from your testing? Without removing biases you are simply fooling yourself.
I don't. Not all listening tests, or measurements, are conclusive.
I think you're playing a very weak hand and your convinction is nonsense. Maybe you are predisposed to making hasty judgements, and this is your way of dealing with it. If so, good on you. But laying that on everyone else, people you don't know and have never even met? Projecting your own character traits on to everyone else is pretty foolish.

Since when has being skeptical and inquisitive been foolish? It's the basis of all good science and engineering, but the enemy of faith.
There are many excellent resources available on bias in research because humans are particularly good at coming to false conclusions.
You have become quite defensive, please don't take what I write as a personal attack.

I don't see you being "inquisitive".. I see things less flattering. But this isn't the place for that.
My process works well for me and yields quite good results, thank you. If yours does for you, then great.
With that, I exit this discussion with you.
