Does bewiring decrease "wholeness" ?

I have been a sceptic about bi-wire hookup, except for the fact that you probably end up with more copper (lower resistance). I have never heard any technical explanation of why bi-wire is better...just the usual "trust me it sounds better".

However, although it may not be original, I have one explanation that has come to mind. On the Hot side of the amplifier output the high and the low frequency drivers are iusolated from each other by the capacitors and inductors of their respective crossover networks. The returns from the two drivers, on the other hand, are tied together, and isolated (just a little) from the neutral output of the amplifier by the inductance of the speaker cable. So the high frequency driver sees "tailings" of the low frequency signal, and vica versa. This theory would predict that the benefits (if any) of bi-wire would be realized if you only doubled up on the return wire.

What do you think? Anyone got a better idea? (And don't just tell me it sounds good!)

OK. I cut my cable in two, (ART monolith), got rid of the jumpers and be-wired the cable to my Proac 1SC and yes, just like the Stereophile review on same, I perceived some added overall clarity and a little shift in perspective and tonality.
Yet, the overall impression a get, when attending a concert in Montreal was reduced, but more importantly, the expressivness, brillance and sublety of atmospheric moods on witch the Mendelsohn violon concerto was builded an appreciated for, became suddenly inaccessible, to say the least. The be-wired version, gave me sound that where dis-jointed or dis-associated with the musical intent of this particuliar genre of music, that I know now, and the salesman must have knowned then....

I second Gthirteen's post. My experience is with the N801's. I will add that I believe that your system should be fairly revealing if you are deciding to do a true biwire setup or else you may not hear the difference. Also, your level of playback and whether or not your speakers can produce a wide dynamic range will affect your perception of the effects of biwiring. When I first began experimenting with two sets of speaker cables it was with a double run of Tara Labs Air 1's. The 801's seemed to wake up and come alive. Everything played so much cleaner and tighter. The overall sound was much more coherant. Of course, I am using a high powered amp with two sets of binding posts that easily sends plenty of current through the cables. Just my two cents.

Ok, I am back, with, this time a more appropriate result, concerning the bi-wired version of the Proac1SC versus its jumper version. I haden done it entirelly properly, so here is the corrected result.
An added clarity was again obtained, sound sources where more distinct with less convergence giving in the process, an added stability to the imaging-soundstage phenomena. Thighter bass and over all tidyness could let in more details as well as more spring or jump to the plucked string guitar or other dynamiquelly contrasted elements.All interesting studio recordinds benefited and male's voices where as real and musical as I know them to be. I doubt that any musical elements has been lost in the process, althought the bass heavyness of the single wired version as help make my mini- monitor sound a little more concert like and the overall added looseness might have contribute to the little extra lyricism and velour like rendition of some female voices and the violon.
All and all, for me and in my set-up, (analogue, tube phono stage, SE 300b power amp.), the be-wired 1SC seems to be a clear gain over the single wired one.
