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?

Dont throw me stones,but i used stones for that with great impact on all count! 

Try some...
The conductors inside the walls feeding from the service panel are already only 12 gauge (or maybe even 14).  I would compare to an off-the-shelf cable and request a refund...there's nothing to debate if it's a "same length" cable and laid in exactly the same position so as to avoid the issue of EM field theory discussions creeping in...or its just variances in inner ear pressure.  Maybe try a different listener?
A power cord has as much effect on SQ as a gas pump hose has on a car's mileage! 
Soundstage is the off-axis of the speaker, it can’t be changed. Now, channel separation, phase mismatch, frequency response linearity do play roles, but a different power cable is incapable of effecting this.
Of course vibration is a big issue, too, and it can be rather difficult to separate the two in terms of cause and effect.
