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

The amp has to absorb current generated by the the speakers to be able to control them. The direction arrows on your wires seem to point wrong 50% the time for this fundamental part the the circuit that the speakers are a part of.

Arrows, when they’re present, are intended to point toward the speakers. That’s because the manufacturer controls wire “directionality” whilst fabricating the cables. Ideally all cable manufacturers should control directionality for all of their cables, power cords, HDMI cables, interconnects, digital cables. It’s only a 50-50 proposition when they don’t control directionality and there are no arrows. I’m not referring to shielded cables which might have arrows for a different reason.

geoffkait, you need to take a course or study the fundamentals of AC ie ALTERNATING CURRENT.  

The electrons in an AC circuit don’t really move along with the current flow. Instead, they sort of sit and wiggle back and forth. They move one direction for 1/60th of a second (60 Hz in the case of the US power system), and then turn around and go the other direction for 1/60th of a second. The net effect is that they don’t really go anywhere.

The electrons initially move in one direction, but then REVERSE themselves and move in the other direction (opposite the arrows on your wires).  The back and forth movement of the electrons in the circuit continues as long as the voltage continues to reverse itself. 

How can this company understand directionality in a place (AC current) where it does not exist?

>>>>>I never said electrons flow through wire. Your statement is a Strawman argument. You might as well say the sky is not green.

>>>>>>Many Cable companies, at least the ones that count, understand directionality. It’s you who doesn’t. As has been pointed out previously, almost all if not all places in an audio system where cables exist are AC. Hel-loo!

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. 😬
