Albertporter, how can one be so righteous about a *lack* of knowledge? I can understand a distain for engineering and science in a field like oil painting, or maybe even making musical instruments, but in a field like audio equipment, which wouldn't even exist without science and engineering??? Do you have any idea how silly that sounds?

Ya know what, I haven't had this much fun in a debate since some kid tried to convince me a grounding kit added a bunch of horsepower to his Honda.

Rushton! Welcome to the down-with-knowledge-fest! So let me guess, you don't know anything about electricity, electronics or psychoacoustics either?

I'm sorry, but I still don't understand. Perhaps you can educate me. Forget about electrical outlets for just a second. They're too simple for argument. Lets go with power cords. So one can measure a 60Hz AC current at a certain voltage level coming into the cord at the male end of the plug, and there's exactly the same 60Hz AC current at the exact same voltage (within .1 volts, or a loss of less than 1 part in a 1000) coming out the other end. The AC power is about to go into a transformer to be stepped down in voltage by a bunch, and then rectified to DC. Then it flows into a rank of capacitors that meter it out to a couple of amplification stages. Oh yeah, that transformer has a bunch of inches of wire in it. And then there's a bunch of feet of wire in the wall, before you even get to the power cord. Don't these wires make the power cord a little moot? Now tell me again how the power cord affects the sound of the amplifier's output? I must be missing something... can you help?

Robin, as Albert already pointed out, electrical/electronics knowledge is not needed for assembling a musical system. Again, shut up and listen. Get a cryo'ed outlet, install it and fasten your seat belt...

WOW !!!
So can anyone respond to my post of 11-12-04 ?
Is the isolated ground system a decent path to take ?
I didn't mean to stir-up a hornets nest !!

Psychicanimal, it's little rude to tell somebody to shut up in the public forum.

Those of you who heard a difference with power cords, good for you. Those who have not, also good for you. I for one am with Irvrobinson but I do replace the stock power cords of all my equipment with some cheap but decent ones. My system certainly looks more *complete* with the cords. Sound-wise Irvrobinson maybe you're right it's in my head. Oh well who cares. The cords look impressive anyway.

Irvrobinson, keep up your postings as I find them quite informative.
