The ARC branded cables from around 1990 were made by Cardas without the "Golden Ratio" wire laying. At the time they must have tried many, and partnered with Cardas. I do not know what their reference wires are today.
I like the older Cardas for single ended RCA connections with ARC equipment.
For balanced I prefer Pro cables like MarkerTek Canare or Mogami.
Ralph Karston (Atmosphere) believes inexpensive "Pro" balanced cables are all that is needed..
Look down this link for his take on balanced.
