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.
