Why power cable effect overall syste sound?


Power cables effect the system sound. This is a well-known fact. My question is why.. specially in case of low power type "A" amplifiers where current is constant. In my single ended 300B the cable creates huge difference. Does it points on power supply PSRR issue? Actually in case of well designed power supply, the power cable should not introduce any improvement. We are spending hundreds of dollars for the 1 meter of cable from outlet to IEG socket where meters of cheap wires running in the walls and it does work. The answer on this question is puzzling me.

It is a fact not known to some it seems.

My ears made the fact as.plain as breathing.

Changes are easy to hear.

I use cables and cords to fine tune the sound to perfection to my ears.

So yes, play and tune your system with cords.

Some deliver warmth, texture and body while others deliver speed detail and transparancy..

No need to spend big money, just play.

First decide what you want more or less of in terms of sound personality. Then read about cords with those characteristics. Now its time to try a couple out.

It always amazes me how much a darn cable can change the sound and my involvement with the music.

You must take some time and effort. Your system and room are unique and a cord's impact on the music will be determined only by your ears and emotional response over time.

Yes cords do play a vital role in finishing out your system to suit your tastes.
I GUESS THOSE OF US WHO HAVE ACTUALLY TRIED AND WORKED AT THIS IN OUR highly resolving systems must be deaf or part of some huge conspiracy? I am amazed at some here on Agon? I must assume that we do not all have the ability to hear the difference. I suppose that is possible as we are all created different.

As far as the argument of miles of wire in the house and throughout our communities before our 3 foot power cord, well why bother with any special wire inside our gear or caps or connectors or any high quality parts? That argument makes no sense to me at all.

Power cords, tube rolling, audio racks, room treatments, speaker wire, IC's, speaker placement, burn - in and tweeks all make a big differnce. If you don't hear them, then that is true for your God given set of ears.

I trust those of you who can't hear the difference either have not tried or really can't. Just don't tell me and others we are not telling the truth or have been tricked.

We must account for the fact that we have differing abilities to hear changes in sound. I choose to believe we are all being honest here and are simply sharing our actual experiences.

I know this to be true in the food business. Not all people share the same ability to taste a change in a food product. As a product manager I have learned some cannot taste the difference when we change a product while others can (blind testing). The same is true for the other senses like hearing.
