Why not?

@holmz nothing wrong with a stout power cable to accompany a stout power supply.

Correct @jerryg123 - but the question is ”does anything become more right with a stout cable?”
In terms of front end gear we have nothing shown so far to suggest that it is “more right” to run a different cable.

Going from a 16ga to a 10ga on an amp seems more right. But iut would be nice to see it.

Nor is there anything wrong with a interconnect and speaker cables built to a higher standard than lamp cord.

Also true.
We have measurement specs for ICs, and also for some speaker cables.

I am not sure from the OPs post whether they are talking about power cables, speaker cables, or ICs.

The speaker cables and ICs have more of an impact than a power cord, and especially on equipment that is running a centralised power supply.

OP… @bruce19

Thanks for your comment. Really interesting question.

You know, at this point in the evolution of technology there is not a solution.

Originally, when I got into this I was a practicing scientist, and quickly I realized there were too many variables to even begin to solve this as a scientific problem… to optimize some stuff and provide an answer. You have to listen. Which, by the way is what science is all about… first observe… this is the foundation. Human hearing is truely amazing and values are highly varied and change over time.

I am fascinated with the pursuit because of a real attraction to music… but remained glued to it because of the positive feedback I received by my decisions that provided improvements in sound quality. I am fascinated by really complex and ambiguous problems… my career follows highly ambiguous complex stuff.

I remember driving at 60 mph across the Black Rock Desert a couple decades before Burning Man rocking out with the highest end Sony Walkman and high end headphones… returning to my motel room in the middle of Nevada (Winnemucca… love the town) and getting immersed in Miles Davis with my 100 wpc stereo with speakers 8 feet apart and incredible imaging. Or hanging my head out the window in Atsugi Japan listening to the best headphone system imaginable (CD player, huge portable head amp) listening to ERA. The rewards, from such effort and commitment unraveling such a complicated problem.

‘Some day I suspect technology will mature and you will buy something that can provide any sound you like. But I don’t think we are close. Fifty year? One hundred? I guess it will happen. But for now… we have to work for what we get. Some folks like the challenge, most think it is a waste of time.

My Ampzilla amps come with a custom power cord that the manufacturer thinks is the perfect match. It's hardwired into the amplifier. Love it or leave it. 

On my previous post above, I cited Musical Fidelity as providing directional RCA cables with their turntables, that should have been, ‘Music Hall’ I don’t know what I was typing, sorry for the (unintentional) misinformation. 

NO!!
