I'm having a really hard time with: "Power cable reduced my soundstage"...

My good friend that is in the business and very very knowledgeable calmed that a well made 10ga power cable reduced his soundstage... I'm not saying it will or won't but why would it? I would like to know the science behind this. I did research on here but not satisfied. I had a pair of Logans and they were wonderful and I used stock power cables and the stage was crazy... I have been making cables for years ( musician ) and know the value on quality... what is the magic?

Tone and soundstage are two very separate performance characteristics IME.

The academic studies of psychoacoustics better explains the difference your friend claims to hear - more so than any quasi-technical explanations you’ll find littered throughout the web and this forum.

The only ways a power cord might affect the sound is if it either, a) restricts current (increases resistance) to the point that it limits the amplifier beyond its maximum current draw capability, or b) its shielding is different, thereby causing an increase or decrease in the total EMI of the system. These two scenarios are both uncommon.

What is most likely is that your friend expected to hear a difference which affected his/her brain chemistry (altered mood) which led to a real perception (not necessarily reality) of difference. That’s about as close as a component can get to creating "magic." Remember that all magic is an illusion.

The same phenomenon occurs when one listens to their system while fatigued, or following a stressful day.
