Best speaker cable for Revel F-208's

"In the past what I have done is use two single runs on each speaker and they would be different manufacturerers one for the bottom end and one for the top."

If you need to do that, somethings wrong. If you match your components properly, cable selection is much easier.

"Im curious if pure copper, copper silver mix and what manufacturers would be a good fit."

Its impossible to say. You can have 2 pure copper cables that sound completely different.

I second The Cable Company. They know your amp and your speakers."

They can also tell you what other customers with the same speakers ended up buying. They keep detailed records of all comments made on any given cable.
