If you read all the information on the Vandersteen website, you will see that Richard Vandersteen strongly recommends that his speakers be biwired. He also recommends against biamping. He grudgingly approves of bi-amping only if all other steps have been taken to maximize the system quality ( i.e. the best level of speakers, subs, source, quality amp, etc ) and only if 4 identical amp channels are used, and if the amps are vertically bi-amped. I suggest that you follow the manufacturer's advice. There are a lot of better things you could do with your money rather than biamping against the manufacturer's recommendation.
Personally, I would not build my system around cables, but that's just me.
As for amp choices, you might look into a used Theta Dreadnaught (I ) . They are usually available in 5 x 200 w configuration for about $3,000. Look for reviews by Richard Hardesty (aka The Audio Perfectionist ). He and Shane Buettner, formerly at TAS, used it as a reference with Vandy 5 speakers for many years. ( the Dreadnaught I supposedly sounds a bit softer and warmer that the II. ) If 100 watts/ch is enough, you could also get a Theta Intrepid, available as new old stock now on audiogon for $1495. You should probably go for the higher power, though.
Some unsolicited advice:
If you don't yet have a processor, and you don't have analog sources, you could use an Oppo 103 or 105 as your processor, and run it directly into your amp. I do that with the Theta and it works great, and eliminates a lot of extra processing; it sounds much more transparent, as well.
Once your system is up and running, your next upgrade should be to get a VCC-5 for your center channel, and then perhaps start adding subs. Find a V2W to use as your LFE sub, and then add another 2W to your front channels. ( you shouldn't mix a 2W with a 2Wq , by the way.)
Good luck!
