Best speaker cable for Revel F-208's

One bit of advice I can offer is that it's not a good idea to mix 2 different cable types to a speaker unless you've checked their specs.
Speakers need low inductance cables which contribute to their resistance, and they need to be matched (or very close). One cable to the high/mid and a different cable to the bass may be of a different type of metal, or have a stranded or solid conductor and could make the sound not coherent from the different drivers.

As far as biwire or using single cable with jumpers, there are many, many threads in the archives.

While you might get some good suggestions from Revel owners, I would offer the following. First, make sure your amplification is right for the Revels since that is arguably more important than speaker cables. Then, order three pairs of cables from The Cable Company and try them out in your system and choose the one you like the best. I've tried the other way--buying cables off suggestions or reviews or because you got a "deal" on Audiogon, but my recent experience has convinced me that using the Cable Company is the best way to go. I chose bi-wire cables from Purist Audio to match with my Harbeths and Ethan was very helpful in telling me how bi-wire works (or doesn't).

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