1. In any given system, the potential of mismatches exists, no matter how unlikely, implying that it is not impossible that a specific wire does not have the best properties to match with an amplifier that for example prefers 8 ohm speakers while the speakers themselves dip to 3 ohms??? Assuming that the current wire is replaced with a different wire...more expensive, thicker, different material, whatever....it may, to some people, sound different than the original wire, but there is certainly no guarantee that it will sound better in that specific system.
2. In any given system, it is pretty well accepted that changing one of the components...amplifier, speakers, DAC will result in a different sound (often better) which suggests that the current wires in use must at least be good enough to allow you to discern the improvement/change made by switching the component...if the wires don't allow you to hear such change, then maybe the wires are so bad they do need changed....but if the wires do allow you to hear the change, then maybe money is better spent upgrading components until such time as you can not hear a change...then start tweaking the wires.
My suggestion is that if someone is going to spend $300 for a Shunyata HC power cord, as an example...that is ok....BUT, they should have someone switch it with the stock the power cord back and forth in a blind test repeated over several days to make sure that the person hears the improvement....before the 30 day return timetable runs out.
Either having more expensive speakers wires, or a fancy power cord will make a difference.
Since if an Amplifier is rated is rated for 8 ohms speaker, changing a speaker wire will not change that fact.
And I am assuming when you said Amplifier, you meant an AVR since most Power Amp are rated down to 4 ohms.
And many speakers will drop there ohms rating, at some frequencies.
That said, in my system I use 12 AWG wires, when many time only 14 AWG is require. But is only a preference thing, to have all the wires the same size
For the power cord, your suggestion to have switching them as a blind test. Is a good suggestion.
That said, changing a power cord will not change a think.
Think of it that way, power is connected to your house. After going hundreds of miles, through power line.
Once inside your place, only the sufficient wires for the Electrical Code to all your plugs.
Changing that power cord, will not improve your signal, since all cord provided with your Electronics.
Have been design to use the one they provide, and are sufficient.
