And isn't it sad when a once engineering-led company like Quad start
recommending that people spend money needlessly, with NO engineering
rationale for the advice.

Ah well, the way of the world...(goes away muttering, shaking his head).....

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?

If you have bi-wired speakers a cheap way of improving
the sound is to put the jumpers back in.

No, it's just technobabble. There is a *tiny* grain of truth in it in
some circumstances, but you'll never notice any audible effect.

As far as I know, neither company produces speaker cable so why bother

Not suggesting your wrong but the logic does seem to be 'logical'!

This should sort the logic aspect:

Highstreet retailers sell speaker cables, its VERY profitable.

High street retailers like it when companies recommend bi-wiring as a
result

Therefore they buy and recommend people to buy gear that requires
bi-wiring.

Thus if Quad didnt recommend it, they would lose out as high street
sellers wouldnt recommend their gear.

since bi-wiring wont DEcrease sound quality, why NOT recommend it?

Excellent synopsis! :-)

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

When I first purchased my B&W Matrix 805V monitor loudspeakers in the
mid-1990s, I used them in single wired mode for a while, leaving the
linking pieces between each set of binding posts in place. There was a
noticeable (although I never tested this under double blind conditions)
difference in sound according to whether the single wired cables were
connected to the "treble" binding posts, or the "bass" binding posts.

Eventually, I decided to purchase bi-wired cables and used the speakers
in bi-wired mode from then on. They did seem to sound more coherent
when bi-wired (with the linking pieces now removed of course), however
I concluded only that they would almost certainly have sounded as good,
or perhaps better still, if they had been properly designed with one
set of binding posts in the first place. Adding more cables and links
etc (whether those are external linking pieces, or internal added
complexity in terms of more complex connections to the crossover)
is surely likely to degrade sound rather than to enhance it.

I have now purchased a pair of ATC Active 10s and have consequentially
left such nonsense behind. Interestingly, I have recently improved
the subjective performance of these greatly (although I have not had
them long, and they were superb to begin with) by investing in a pair
of Partington Dreadnought Ultima stands, which are very heavy and inert
and position the loudspeakers at the perfect height as an added bonus.

People who bi-wire as a rule don't usualy think.
Therefore it will not cause anything.
