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?

Second of all... it is true. 

Ok
1 He is very knowledgeable.

2 The cable is certainly well made.

3 Compared to a couple of high end cables he own’s  and reps... the sound stage was reduced.

1+2+3= go together

he was kind enough to take part of his busy life to test my cable against some big boys... he is going to keep it for a month or so to burn in then test again.
In my experience, shielding tends to close in the sound (although some system really need it).   If with this new cable (op) the soundstage is reduced it could be that some hum is coming through and screwing up the perception of "air" and "placement".
I’m pretty sure shielding can’t deal with the rf coming in on the AC line. Or with the rf generated by microchips, among other things.
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?
