Matchstikman; just for the record, bi-wiring and bi-amping are NOT the same thing, and I agree with Joeavid's post above. Also, as it's generally used in audio language, using subs is also not considered either bi-amping or bi-wiring.
The Vandersteen manual does strongly recommend bi-wiring and explains well how to do it. Vandersteen also recommends passive bi-amping, but if you're really not "into" this audio stuff, leave bi-amping alone, and as I stated above, the sonic gains are minimal anyway. One GOOD amp is better than two mediocre ones.
Keep it simple man and enjoy the music. If you are going to get Vandersteen speakers, whatever model, please, please, please do yourself a favor and get an appropriate owners manual-- even if you have to pay $5. for one from Vandersteen. Good Luck, and Cheers. Craig
