You guys should just try this stuff out. It has nothing to do with distortion levels, measurements, or any of that ********. Until you actually know how this stuff works on the theoretical and practical levels, by which I mean engineer your own DAC, cables, etc. from beginning to end, just listen to it. One thing I learned is it is never about knowing the equations. All models are wrong, and some models are useful. Any ******* can sit at home on wikipedia and memorize equations. Take home something like a BDA-1 and plug it into your normal system that you know by heart, and you'll hear the difference.
Also, here is an excellent article on feedback in amplifiers from a guy who makes better amplifiers than the one you have (probably). https://passlabs.com/articles/audio-distortion-and-feedback
Were I a moderator on sound science this load of bull crap would be nixed. You tell me how the electron flow is having effects flowing in one direction, then wish to ignore that the very effect you are referring to on the very cables is an AC phenomenon which has electrical pressure in one direction then the other. Meaning your supposition of the effect doesn't happen, much less the info Steve Eddy has supplied also abrogating such claims.
Then the claim it has nothing to do with distortion levels, measurements or any of that stuff. Yeah, right, sure , just go with the feel right? Bull crap garbage. If it doesn't alter the signal it doesn't sound different. And altering the signal is the definition of distortion. All of which we can measure far below human abilities to hear.
Then the ridiculous article by Nelson pass on feedback. Look what matters is the signal coming out of the output. Do it with no feedback, low feedback or huge feedback and it doesn't matter if that result is clean enough it is inaudible. Not to mention the hubris, totally unjustified supposition that Mr. Pass' products are better than what I or anyone else has. Guess what? I have owned a couple of Mr. Pass' products including a no feedback design. What I have is better, both in how it sounds to me, and in how it measures, not to mention how well it powers my power hungry speakers. So much for your garbage suppositions.
Finally are we to take it that you have engineered your own DAC, cables, speakers, amps etc. or otherwise by your criteria all the bull crap you just spouted is something no one by your criteria should listen to. Kind of crazy is exactly how I would characterize it. Crazy! Man! Crazy!!
