Hi - I've just bought some speakers, JMLab Chorus 715, marvellous. Anyway,
something in the setup instructions intrigued me - bi-wiring "reduces or
eliminates any problem caused by the bass drivers feeding any signal back
to
the amplifier. This signal intermodulates and spoils the sound quality of
the midrange and treble". Er, what?!

I don't bother with biwiring as a rule, but should this cause a rethink?

Heh heh! Good old Rob - we haven't had a 'Biwiring' thread here for, ooh,
let's see - must be days now!

It's really quite simple, reading those instructions has already caused to
you rethink. My suggestion is that, if you already have the necessary wire
kicking about, you try it yourself and see if it makes any difference to
you. If not, then I suggest you leave the speakers bi-wired and keep 'all
bases covered'. (Placebo Effect alone makes this the 'better' option....
:-)

Biwiring is a bit like Ghost Stories - no conclusive proof either way** so
the myths continue and have done so long enough for fair-minded people to
think 'it's gone on for so long now, there *has* to be someting in it.....'
(My take is that there is almost certainly a difference, especially if there
are poor quality or faulty components in the equation, but that it is likely
to be so far outside the audible range as be entirely academic.)

Out of interest, on the subject of bi and tri-wiring, Ruark say "Where
possible we recommend you take advantage of this facility as the only extra
cost is that of one or two extra pairs of speaker cable. etc etc." They make
*no* mention of sound quality (improvements or otherwise) whatsoever. I
think they are also just 'covering all the bases' and by implication they
would appear to not expect you to spend too much on the speaker cables, in
any case.....


** Unless *you* know different - anybody here prepared to claim that
bi-wiring produces a palpable improvement to a particular speaker/amp combo?
