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

5% gain is quite a bit to expect with any pwr cord change from just a stock thick gauge cord.
I’ve been using upgraded cords for a long time,generally make my own,and without question they do lwr the noise floor,have better defined dynamics,and are generally smoother and more refined across the board.

I’ve owned many class d amps and I found that with all of them,they like being powered up all the time.My latest amp a Lyngdorf 2170 definitely likes being left on,not on standby,all the time for the very best in sound and also is ready to go at any time.

I recommend that you try a reasonable priced cord and listen for yourself and compare to a stock cord.

“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.

Al,
Thank you for the clarification and I do understand both of your points of view but I’m still curious and I’m going to order one to compare.
If I like it better than what I presently use I will keep it,if not it will sale.Proof will be in the listening comparison for me.

Just curious,
Kenny.

Jetter,

+1 very good ,I would say you are plugged in and tuned in as well today.

Still Laughing,
Kenny.

Oops forgot the dc pwr cables powering my Network devices.

Al,

“But a signal having both DC and AC components is nevertheless "operating in an AC circuit," it seems to me. 


So the only audio-related cables I can think of which are "not operating in an AC circuit" are cables conducting the outputs of DC power supplies that are external to the component being powered.”

This is how I have always understood this too but I may be wrong or missing something also.

As always Thank’s for your well explained statements,
Kenny.
