Science may not have the answer for everything, but that's not a reason not to ask pertinent questions. The ear is a marvelous measurement system, but it is not infallible and on the head of an unskilled listener, it's not particularly reliable. By this I mean the results are not repeatable in a statistically meaningful way. I suspect a few readers will say "Who cares?", and they may be right. Still I wonder why I can't find a reasonable explanation of why power cords make the sonic differences that some attribute to them. BTW, in no way should my comment be construed to denigrate any persons ability to hear or the validity of what they report. I'm just interested in an explanation.
How come a power cable changes the sound?
A good power cable definetely changes the sound but how ? A cheap 2,5 mm copper cable comes upto wall outlet and comes through a fuse (which has very thin wire) than we add a huge heavy power cord which cost 500$ than the sound of the equipment has big improvement What is the technicial logic and magic out of that ? Thanks..
