Power Cables

Power cords are directional because one end is terminated to plug into the wall or power conditioner and the other end plugs into the audio equipment.  I can’t remember ever seeing one that wasn’t.

Really interesting that the article above says the wiring in the walls is usually pretty good.  

My Levinson 333 has no option to change the power cord.  I have wondered about running 30 amp service to it and swapping out the plug as specified in the manual.  I wonder if the difference would be audible for high-transient situations.

I have a couple of different power cords and look forward to trying them once my Stellar GCD arrives next week.

Why do folks insist that "Power Cables" need to have a bandwidth equal to that of a very high-spec amplifier’s audio bandwidth? Are you people INSANE? We are talking about 60Hz AC here!
If your power cords are carrying Khz range signals or noise there is something horribly wrong with your amplifier that needs to be corrected immediately, if not sooner because you are essentially operating a Radio Transmitter in violation of Federal Law! ;-)

I just measured the drop across the 5.5 foot original power cord on my 1964 Scott 222D Integrated Amp.  and found it to be 0.2Volts [120.8VAC at the outlet and 120.6VAC at the circuit side of the power fuse. This is with 18guage lamp cord!

Yuk, yuk. No, I mean really.

Re. Pop Quiz " How come HDMI cables are directional?"
They are not unless they have active circuitry built in to compensate for unusually long runs. ;-)
