Speaker cables for Vandersteen 5As?

Any 5A owners out there using Nordost Valhalla? I was thinking about going the Valhalla route, but I'm also considering a biwired shotgun set of Audioquest Kilmanjaro.

I know Rich Hardesty and Shane Buettner both have 5As and
both use AudioQuest cables with great success.

I know to try before I buy, but I'm just looking for some real end user results and their comments.

Let me know your thoughts.
