Do CD Transports benefit much from upgraded power cords?

It’s a fact within the boundaries of that measurement that was posted (not sure what the source of that information is by the way) but it doesn’t apply to audio.

It’s completely irrelevant. And as such isn’t s fact when discussing impacts of cables in the system. 

It's still a fact whether it pertains to audio or not.

It may not be perceived as relevant, but that doesn't change its status.

Don't read too much into my simple statement because it doesn't warrant in-depth scrutiny. It's just a simple statement that doesn't lean to any side.

Agreed. I think I’ve explained how and why. Ultimately everyone decides what matters to them the most. I wouldn’t waste thousands on power cords if your components and room acoustics don’t warrant that.
