Shieded power cable with small gauge conductors

Curious why it needs to be shielded and small gauge conductors? Are you referring to it being small gauge because you want a flexible cable and what is your budget? Not knowing much to go off here, I'll throw out Kimber PK14 Ascent or older, used Gold; pretty sure same cable with a new name. Not a shielded cable, but very flexible. All my power cords which two are Kimber PK10 Golds pick up no noise whatsoever. My experience is a well designed unshielded cable is more open than a shielded cable, for most cable types except for a turntable. If you truly do need a shielded PC, verify if the shield is floating or tied to the ground at one or both ends. If you haven't experimented with an unshielded cable I would recommend giving it a try. Always tons of used PC's out there, so if you're watching the budget, buy used over new or build your own as well.

Shaq,

Build some yourself if you'd like.  DH Labs makes reasonably good cables at normalish prices of $5/foot.

I appreciate these ideas.

The recommendation that my power cable have good shielding and small gauge conductors comes from the maker of my the power supply, the Sonore Series power supply, which is the power supply for the microrendu streamer, 7 VDC.

They recommended a Cardas cable that costs about $500 and I'd like to either custom make, or find a cable for less than that.
