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

Well, in the case of the new Hurricane power cord from Audioquest you can attribute part of its very high performance to wire diectionality

Once again, a wire that acts like a diode, "snake oil". Brilliant it's trying to rectify the mains, which is AC (alternating current) and changes 60 x a second, more "snake oil"

>>>>Oh, geez, you’re just regurgitating 🤮 what costco_emoji keeps claiming - that a wire acts like a diode. Hey, get real guys! Have you run out of ammo? No one says wire acts like a diode. After all this posturing as some sort of electronics EE guru and you still don’t even know what wire directionality means. Unbelievable! 

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.

Extra credit: Why would Audioquest control directionality for power cords if it didn’t affect performance? Do you think naive gullible newbies are scarfing up the new Hurricane power cords because they think that directionality is cool? 

“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. ”

+1 on this simple statement.


Kenny.

Kenny, no, Geoff's statement that only one direction of the AC current is audible is completely incorrect.  As I said in one of the recent fuse threads:

... when AC current is moving toward the component in the "hot" conductor it is moving away from the component in the "neutral" conductor. And vice versa. So it is moving both toward and away from the component at all times. And a mains fuse is in series with the current in the neutral conductor as well as being in series with the current in the hot conductor, via the primary winding of the power transformer.

And simultaneously, as I'm sure you [Geoff] will agree, energy is being transferred unidirectionally, toward the component at all times, in the form of an electromagnetic wave comprised of photons that is distinct from although intimately related to the AC current....

I will have no further comment on this matter.

So if in fact Audioquest's control of the direction of the wires in their power cords provides any benefit, it is not for the reason Geoff stated.

Al, what I’m afraid you don’t understand, is that both wires are directional. Both wires should be controlled for directionality. Which is obviously what Audioquest does. Nice try anyway. Then you will hear the effect of directionality, because the audible direction for both wires will be toward you the listener. We don’t care what the wire sounds like in the opposite direction. I don’t think I can say it any plainer.
