Leftyfox,
Hi
I'm using Cardas with the ends soldered. My dealer made them for me. However, I think any good cable will do. Interesting that Totem recommends bi wiring. I can only say that in my situation it is an unnecessary expense. Actinote are good cables, much better than my Wireworlds, so this may impact the result. It's possible that bi wiring is cable specific. However, have you noticed that many of the high end speakers don't have bi wiring capability? Says a lot I think.
What amp are you using?
