I haven't felt the need to.
Who's him? Not to brag, but I have better ears than him just due to age (I'm just 21 and still can hear 20 kHz, and it is really unpleasant).
First of all, the ears convert the sound pressure into electric signals, so if the ear does not pick it up, it does not get converted as part of the signal. Second, I wouldn't trust the brain as an audio analyzer, it is full of biases and psychoacoustic effects that cannot be fully separated from the goal of a test.
Lol, hmm you realize that's like saying you can shoot a better jump ball than Lebron James when you rarely shoot professionally, right? Or knowing how different various golf clubs at various price affects your game if you don't play golf, either? Or how much better a $500 bottle of wine tastes vs a $5 bottle, etc.
As for Paul McGowan, he's only a co-founder of PS Audio, a full-time engineer himself with decades of experience and who has listened to countless systems and cables day in and day out. In other words, the sheer amount of experience he has easily eclipses your so-called superior (doubt it) 21-year old hearing. Same with Gordon Rankin who literally revolutionized digital audio by introducing asynchronous USB standard to the audio world and he himself had said USB cables make difference after listening to 1000s of USB cables as part of his job.
In other words, why wouldn't I trust their words and their experience over yours?
