Did Amir Change Your Mind About Anything?

    IF you’re interested in the possibility of improving your system’s presentation, have a shred of confidence in your capacity for perceiving reality and trust your own senses: actually TRY whatever whets your aural appetite, FOR YOURSELF.     

Trust your senses, plural, and you will definitely fall in the ditch of wasting money and effort instead of sitting back and enjoying music. 

What you should do is do what you preach: trust your ear and only your ear.  If any other senses are involved, then you are not assessing the sound of something.  Learn how to do a proper listening test that has only one variable (what is being tested) and do it to rule out chance (i.e. repeat a dozen times) and by all means you can trust your ears.  

Yes, there is a bit of work involved in that.  But I assure you it is less than attempting to convince people to abandon common sense and audio science/engineering. 

If you can't be bothered at all, then there are people like me who do the legwork for you and present you very useful information to base your audio purchases on. Huge number of your fellow audiophiles are doing exactly that and are better for it.  Think hard as to what they know that you don't.  Surely they know your method.

Theories have never proven or disproven anything. It’s INVARIABLY testing and experimentation that proves or disproves theories/hypotheses.

That’s right. Your theory is that this and that makes a difference in sound. We put the very same person in a listening test, while keeping their lying eyes out of the equation and all of a sudden that difference disappears like fart in the wind. What then happens is that you deny the results of these experiments. You much rather not know it seems. But again, people are realizing the gig is up here and adopting a much more rational method to judging audio gear. They are saving huge amount of money and getting much more performant systems to boot.

Yes, he did change my mind, about power cables.  He proved, using signal subtraction, that the signals generated by devices from different power cords are identical.  Any difference you heard is confirmation bias, as the signals feeding the amplifier are IDENTICAL

I’m disappointed nobody responded to this observation.  Do you guys agree that Amir is right about power cables?

He didn't change my mind about power cables. I already knew enough electronics engineering to know that if safe and sensibly designed, they can't affect properly designed audio kit performance.

What @amir_asr has also shown (if you read further than the headlines) is that even he sometimes hears a difference when he changes things, but that the perception is unreliable and an effect of perceptual heuristics.
