Tvad,
Do you mean fromyour reply that the woofer wire is less critical than the tweeter wire, or that HD 12 or Canare would be fine for both?.
I currently have a Blue Heaven single wire, as well as a set of inexpensive Rapport wires that I'm trying as a biwire. I'd forgotten Gamut's biwire capability , and VSA recommends a shotgun system as giving the best sound, leaving the link wire out. I will be trying that as soon as the speakers have some hours on them.
