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

I've heard the tiny improvements or worsening of the sound for that matter, in regards to power cords. While I never experimented with the mega buck priced cords, do they offer any real world improvements over more modestly priced cords? It seems to me there is just so much one can do with the AC coming from one's outlets. I suppose I'm just stating the obvious. I'm not an engineer of any variety. lol.

Jetter,

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

What color jacket works best to maximize the sound from a power cord?

Pink

I hesitate to answer the question white because the answer would probably cause angst and consternation white among the usual suspects. I don’t have to white mention any names. Also because this subject enters some areas way beyond scope white. I’m not saying this to be coy white but because I don’t wish to turn this thread into yet white another mud fight. 💩
