New expensive power cord for amp and no change in sound?

Imagine power supply that works like this. You charge big battery from mains, disconnect it and then use to power your amp with clean DC, disconnected from mains. No noise from electrical lines.

So ideal power supply should work exactly like this, rejecting noise and interference. Amp schematics and parts placement may be more or less sensitive to what comes from the AC mains.

Different amps have different designs and different power supplies. Thus some are more sensitive to power cables and some less. Perhaps yours is in the “less” category.

@roxy1927 power cord change from original one one of respectful manufacturers, shouldn't make any listenable difference, assuming original cable is healthy. Many used separates are sold with random, no-one knows, power cords, and in that case, replacing it makes sense.

Power cords can make a huge difference. This difference can be on par with buying a new amp (component upgrade). But unfortunately, cost does not aways dictate compatibility or performance with your gear. You just have to go with trial and error. Its just like buying interconnects, again, trial and error, system dependent. 

Well then Pass is a well known and admired popular brand in the audiophile world. I would like to know if others have used up market cords with Pass and found they did improve the sound.

Or does everybody who buys Pass use the stock cord?

I would appreciate if Pass owners and there must be a number of you would respond and let me know what results you’ve found.

The there is always the option of changing the amp. That will surely change the sound of the power cord. 💡
