Why do you think Bi-Wiring improves the sound ?

Now bi-amping is a completely different animal. I can get into that. 

RE: Whip-Shaw's post quoting Vandersteen.  If you bi-wire doesn't the wire carrying the signal to the bass driver carry the FULL range of the frequency to the bass driver but the treble frequencies are filtered out by the crossover before it gets to the driver?

And doesn't the wire coming from the amp to the tweeter carry the FULL range of frequencies to the crossover and then the low frequencies get filtered out before it gets to the tweeter?    

I do not think bi-wiring or even bi-amping eliminates the crossover does it? It simply directs the signal to different sections of the crossover. One goes to the low pass filter, the other to the high pass filter.  The full frequency of the signal is delivered through EACH of the two wires only to be filtered after it gets to the crossovers.   So the bass frequencies STILL interfere with the treble frequencies in each wire, as they would if only one wire was used.  CHANGE MY MIND. 

Maybe getting higher quality jumpers rather than using the typically crappy factory ones would be a factor too. 

Well tabonuco  could you reword that in English please? 

If it is easy, do it. What can it hurt to find out and know for yourself? If it were a PITA to do, then I would have the same concerns your OP had. But since it would be an easy experiment, do it and report back. You know that further contributions to this thread will continue in the same vein with those advocating one or the other side. (as usual). Have you EVER seen a subject when it comes to our hobby where there is a reliable and absolute consensus? At best these questions are an academic exercise. At worst they are contentious arguments.

I have come to realize that all the opinions, reviews, theories, experiments, discussions in the world do not trump my own experiences. I am the only person who knows what I like and want. And it is EXPENSIVE and time consuming to go through this journey. But your particular situation here is not all that expensive nor time consuming to try. In fact, it could have been done in the time it took this thread to peter out. 

And my reading reviews has done more harm than good for me in the outlay of money department.  I really have not improved the sound of my stereo since 1984, even though I have been through over a hundred components. I have circled back to a very similar system I had back in 1984 much to my satisfaction. If only I had just left it alone.
