Has anyone used cardas romex

Building a room and thinking about using high dollar wire for 2 dedicated circuits
I replaced the romex for my dedicated line with VH Audio's 10 awg cryo'd romex. It's affordable (by audiophile standards) and seems well made. It resulted in improved dynamics and slightly better resolution.

I don't know about the Cardas romex, but somebody around here has probably used it. Good luck.

If the Romex i delivered in a spool - at least some of the effect of the cryogenic treatment is lost upon un-spooling it.

Careful attention will have to be paid to how its installed, if pulled through pipes, twisted, secured with clamps etc like normal romex is typically pulled - IMO it would not be worth the extra expense.

Best of luck
