Should power cords for power amps be shielded?

The King Cobra is a ne plus ultra cable with 600 individual oonductors, I would expect it to sound fabulous compared to most other cords, shielded or unshielded. I believe Shunyata employs a mind-bogglingly elaborate conductor braiding to achieve the effect of standard shielding. There are exceptions to frustrate every "rule." I'm looking for guidelines -- generalizations about "most systems, most of the time."

Hello, Elizabeth. I see from your many initiated and answered threads that you have loads of experience, including DIY. To answer your questions, no, I don't have a tangle of cords, and yes, I use a power conditioner -- of sorts, a PS Audio Quintet. I use (unshielded) Audience cords on my front end (transport, tube dac and pre) and shielded (currently) on my ss monoblocks. Perhaps I
have the optimal arrangement reversed. I intend to replace my Diamondbacks with DIY and am looking for the best budget combo I can put together. Right now I'm considering DH Labs (unshielded), VH Audio (shielded), and Cryomax (shielded) wire, but am open to suggestions. Maybe it's six-of-one-half-dozen-of-another and I shouldn't be fretting about a choice. Besides attempting to understand sonic characteristics of the different types of wire -- coloration, extension, transparency -- I'm trying to get max bang for the buck.

I have another thread on power cord wire.
