Bi-wiring/Bi-amping...worth the fuss and expense?

The advantages of bi-wiring may be situational, but to say that each wire delivers the same signal is misinformed or disingenuous about the arguments put forth in favor of bi-wiring - about which many people disagree.

The main argument is that having separate wires for highs and lows carries different signals back from the *speakers*, i.e., back EMF. It doesn't have to do so much with carrying different signals from the *amp* in question.

The Vandersteen site has one of the more concise faq entries on this subject.

I have the Dunlavy SC-5(s) and vertically bi-amp and, of course, bi-wire. This speaker design is very current hungry and equipment picky. There is a substantial difference in
dynamics and low bass performance I believe in the bi-amp arrangement.

Hi! My opinion? Well, bi-amping can be great with certain speakers, but makes little difference with others. Same holds true with bi-wiring - perhaps B&W being a rare "must" even by their own recommendation. Don't forget that some wire mfgs. offer a split wire in one sheath which isn't true bi-wire but is close and less expensive. If you do a true bi-wire meaning 2 seperate runs of wire, remember that you should use better wire for the tweeter/midrange and can use less expensive for the bass, but be careful of how you make this match since a mismatch can lead to some weird phase problems. I think that the best solution for most speakers is to get a great amp and pair it to the most expensive speaker wire in a single run that you can afford. This will sound better than bi-wire or bi-amp. Look for a pair of Transparent Ref. wires or Transparent XL or MIT Oracles. I have auditioned a lot of wires and still think these two companies are the best.

What about going with Mono Block?...Does going with Mono Block with Bi-Wiring Sound better that running with two amps
in Vertical Bi-amp mode?

In my experience the more you split up the music signal between different cables, amps, drivers, etc the more disconnected the music sounds. Sure you hear more apparant detail, soundstage etc. but the music's message gets lost.
