Since biwiring is not an issue because you're using 4 channels, the only thing that remains is cable choice. Opinions vary, but I recommend using the exact same cables for all channels. Some people try to use different cables for the highs and lows hoping to get better sound. If that works for you, great. That's all that matters. But every time I've tried it, I wasn't happy with the results. I could always hear the 2 different cables.
If you want to learn more about biamping and biwiring, go to Vandersteen's web site and download owners manuals for something like the Model 2 or 3. They do a great job explaining all the different terms and options. Also, Vandersteen was the first one to come up with concept of biwiring.
