BI-AMP OR NOT?

Hellow fellow audiogoners,would like your opinions or advise about what I might do with my system. I have a pair of von schweikert vr3s I am thinking of bi-ampping them .To bi-amp first thing I will have to do is add an extra pair of speaker post,for the woofers. Just have one pair right now.I should be able to do this, because there are two set of wire going to one set of speaker post.The next thing would be finding another forte model 5 power amp,100 watts per. I have been told this is the best way to bi-amp using two identical amps.Question is, would the benefits of bi-amping with separate amps for mid tweeter and sub,knowing than bi amping would free up a lot of sound for each amp and speaker because each amp would not have as much work to do to deliver the sound.Or should I just get the biggest amp I can, or maybe a 200 watt forte. Your thoughts would be appreciated. Thanks maxwell
