ok, maybe i like it because:
1-i can
2-it does give me extra control without using the 10k treble control(trim level on my b&k amp)
3-i swear i may be a bit louder using 4 channels instead of 2(when i did this i thought i knew the pros and cons)but it cost me no money when i biamped
one day maybe i will go through the motions to build an active system but till then i will biamp my b&w's and like it. i would venture to say that if anybody could and would try it without spending any real money.do it.check it out.you be the judge.it is your stereo.
i like it.
just my .03
