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

 the benefit of a 10 gauge wire from the electrical panel is to achieve a benefit from lower impedance and Power availability for all those Quick changing frequency needs. Clearly there's enough power to run the device but that's not the point.

The power cords would be connected to 600 W mono blocks.  
 

What about shielded and thick cables? Also it’s a 20 amp circuit breaker.

I am a big fan of shielded cables. Because it's nearly impossible two separate and space out all the cables in most rooms that have hifi equipment.

I thought correct Terminology was impedance for alternating current and for direct current its resistance.

Don't understand what you're saying here

Watt meter is nice but it doesn't in my view accomplish everything you want.

Not sure it measures the extremely high speed changes in Power fluctuations needed for Music.  
Isn't the benefit of larger gauge wires throughout the electrical food chain to avoid any unnecessary impedance when power demands occur?? As tiny and subtle as they may be for all those gentle nuances in sonic transmissions.

To make it easy I rated everything the best I could doing it very carefully and make it easy as I said the total came to an average of 7.6.

Is that helpful?

I will rephrase the question about the need for a 10 gauge power cable.

Would it be better to have a 10 gauge power cord that plugs into a 10 gauge dedicated circuit outlet?

Most things in this world we don’t really need but many a time it makes things better.

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.

It's not about having enough power for the speakers. It's about improving on the sonic benefit of a higher gauge Power cord. Mackintosh is a bit narrow viewed on this issue. Very perplexing

As my teeny tiny brain tries to absorb everything in this thread I am left with an additional question.

I use a power conditioner, a transparent power isolator, and I wonder what the internal wire gauge is to the various outlets on the back of this device that I plug into.

To me this seems like a really good spec that no one talks about. Why is this?  Maybe Tucker Carlson can shed some light on this.

Electrical wires directionally created? Ie. Does it matter which direction wires are installed between the panel and the outlet??
