Power cord replacement suggestions

Yes. Thank you, never assume with me. I just wasnt sure if the conductors in the 15 amp cord were smaller and thus heat up if on a 20 amp circuit.  Never studied electricianomitry. That's why i look to you guys for knowledge.

There are no 'dumb' questions. We all have to learn.

The 20 amp circuit allows more current to flow than a 15 amp before the breaker trips, hence the recommendations to use 20 amp for your stereo wiring. Things like amplifiers can have transient power demands that a 15 amp circuit might 'stifle', the 20 amp gives a little more headroom.
I am probably using the wrong terms, but I hope you get the idea.

Chrisr, don't want to start an argument; however,manufacturers are well aware that there are countless power cords better than the ones they ship with. Power cords as expensive as good equipment can be such,that if used with high enough quality equipment,get the chance to show their value.
For example my MIT Oracle AC3 is a non-networked power cord that will literally 'blow away'
standard p/c's shipped with even good equipment.
In a similar vein, some may argue that 'cotton is cotton' but; anyone in the industry would scoff at that comment. The fact many people don't know the facts doesn't change the reality. I hope you won't buy the '100% copper means it's as good as it gets".
