Can a power cord increase the resolution of an Class D (SMPS) amp by more than 5% ?


5% in relation to a stock power cord.

I can’t really trust dealer comments. I am more interested in reports from audiophiles. 
Whats your story? Did you manage to increase speed and resolution of your amp ? (without losses in the bass area)

For the record, a minor correction to Azbrd’s post just above, with which I suspect he will agree: "1/60th" should be "1/120th," i.e., half of a cycle.

I assume you mean aside from the fact that his entire post is a Strawman argument. To which I suspect you will agree. 😬
Well for some us the world is flat and others its round.

If you dont understand how electrons play a roll in an electric circuit how can you understand that arrows on a wire are meaningless.

60 hertz(meaning the current changes direction or polarity 120 times, or 60 cycles, a second). (In Europe, line frequency is 50 hertz, or 50 cycles per second.)

What is the definition of a "strawman argument"?  If you mean my point is based upon real science and understanding how AC current actually works and not some vudoo marketing pixie dust that this comment is based on:

"Ideally all cable manufacturers should control directionality for all of their cables, power cords, HDMI cables, interconnects, digital cables."

I would not want ANY cable in my system, home or data center that I work in that claimed to control directionality and as it turns out I don't and none of my other audio friends do either.

"You’re right about one thing, the AC current does travel in both directions. But only one of those directions is audible. See if you can guess which one. A prize for the right answer."

The answer is both. How else do you think you build a bipolar power supply? It's the negative phase of the AC waveform pulling half the secondary negative.

>>>Whatever.

Electrons are only charge carriers. The signal, the thing traveling through wire at super high speed, is photons. Pop quiz: do photons have mass? Maybe you should get your money back from the high school you went to, with your friends.

Strawman argument is defined by putting words in someone’s mouth as you did with electrons. Follow?
