I would not use a Audioquest bi-wire speaker cable. Their cables are excellent design, but they are normally just 13awg or close to 12awg cables. When you do the bi-wire option, you are just splitting that into a 14.5awg + 15.5awg cable.
I would recommend using a non bi-wire cable and connecting it to the top (tweeter) binding posts. If you don't like the jumper block between the binding posts, then get a high quality jumper cable. You lose current capability if you bi-wire an Audioquest speaker cable.
There are other speaker cables which are fine bi-wire. These are cables that are 8awg to 10awg to start with.
