Do I need 10 gauge power cord if I have 10 gauge from panel?

I just installed some dedicated circuits with 10 gauge electrical wire. But now I have to consider replacing my amp power cords because they are 14 gauge or higher.

Is this really necessary and any recommendations on quality 10 gauge power cords that I should buy?



I’m with @ghdprentice on this one:

"Only when comparing to other cords. This is not a pursuit with absolutes… maybe the desire, but we live in a world of imperfection."

As with many audio pursuits, experimentation is the key to success. Hopefully, you can get your hands on some good examples of premium PCs and give them a listen.

IMO, adding hospital grade plugs will have a larger sonic impact. I have 2 dedicated 20A lines for my stereo. It turns out that with everything running and playing music, 2 amps, preamp, phono-pre, dac, cdplayer, turntable, draws only 2.4 Amps. So, the 20 Amp circuits were unnecessary. 


What speakers are you driving with the commercial series Crown amps? As per their own recommendations, they were designed to be used in music halls and live performance studios, not for a homes living room. Also these were supplied with a 30A plug on a 10AWG  cable, to meet the commercial requirements of that amp.

This whole thing isn't making sense to me.

This really didn't seem to be a difficult question but I guess it is.


I was just curious if the last few feet make that much of a difference if you use a larger gauge Power cord when using a 10 gauge wire from the panel to the outlet. The bulk of the muscle effort comes off the panel to the outlet I would guess and maybe to extend a 10 gauge to the amplifier is very important.
