power cable

Yeah, usually the power amp, though it can depend on the cord and on the equipment. For me it is Purist Audio Dominus Ferox, either power amp or integrated, either SS or tube. I have Top Gun from Custom Power Cord Company on the sources. The Dominus works great everywhere but especially on power amps. Heard good things about Shunyata and some Audioquest cords but never tried them.

@guitarlenn55 - if your system in on the budget end of the scale - use it on the Source components

Budget oriented source components tend to have poorly designed power supplies so good cables will pay more dividends, whereas the amp will have a more substantial power supply. so the cable will not have the same impact

The further up the scale you move then you have to spend a lot more on a power cables to make a similar impact on a source or amplifier

Paul Speltz of Anticables suggests the above.  But see what works for you.

Unless current power cables are of poor quality (e.g. very thin, or noise-prone), you will not hear any difference. That's true based on physics. However, the new cable may give you better sound based on imperfect human-being nature, which tends to go to some destination you hope.

Why, om earth, many people try to waste their hard-earning money to believe some maker who makes snake oils?

@guitarlenn55 why do you think’ replacing PC will change sound?
