@Mzkmxcz We might be talking about different things. Mains leakage and EMI are important considerations. I was referring to over-engineered power supplies as a means to improve sound quality and dynamics. It’s long been known that using large power supplies rated many times in excess of what is “required” provides better sound. PS Audio was one of the first ones to discover this and bring it to market with their preamp line and then eventually all/most of their products.

I am indeed not talking about power supplies, which can make a difference. I’ve seen products that have power supplies restrict their performance as the amp modules were capabale of more wattage than the power supply could offer. And thus, since more wattage means more dynamics, I agree with you on that point. Not so sure I agree with over-engineered and rated for more than what is needed; like I suggest more wattage for power amps that what is needed as most amps have more distortion at the top of their range and more heat dissipation which can reduce its lifespan, but if an amp didn’t have those issues, then I wouldn’t reocmeneded more wattage than necessary, same goes for power supplies, now I don’t know if the power supplies aren’t as good when you get close to their limits, if they do, then yes, get a better one that what it’s rated for, though I would argue what it’s rated for is thus incorrect.
I am disagreeing with the fact that changing the power cords can make your bass deeper and give you a wider soundstage.
So the guy 'disagrees'? He is just guessing/ making up fantasies. Good luck with that stuff.He says folks need to prove (to him?) NOT. all I need is to listen, I do not need to prove to him anything. Nada, zero. Ever notice these naysayers jump into threads promoting PC and IC. They never seem to have their own threads... Why? No one would post to it! LOL
I would like any possible explanation on how a power cord can extend treble response.
Indeed, if it sounds better to you, go for it. Just keep in mind it’s all placebo.
Here’s a recent news article on that even if knowing something is a placebo, it still works, which covers the bases for those people saying they never believed in it before, but now do. If sugar pills can legit cure illnesses, you can bet it can make you think the bass is better.
