AC in-wall cbl for ded circ - enlighten the idiot

i am having an electrician put in a dedicated 20A circuit to a FIM outlet for my audio system. initially, i was just gonna have him use 10 guage whatever wire he recommended. now i've done some research, though, and i've found that some companies that make PCs and ICs are making in-wall cable for exactly what i'm doing. jpslabs sells ac in-wall cable that's ludicrously expensive (15 - 20 a ft) and virtual dynamics sells one that's cryo'd, cable-cooked, and reasonably priced (3.50 a ft).

now, the jpslabs cable is UL/CSA listed for in-wall use. as far as i know, the VD stuff isn't.

my questions are as follows:

is this something i with which i need to be concerned?

will i be breaking some code if i install the VD stuff?

with the in-wall cabling police set up a perimeter around my house and bust me the next time i leave for work?

if so, do they allow for conjugal visits whilst serving time?

and, does anybody have any experience with either of these? (the wires, i mean)

thanks and good day to ye,
