I have a Musical Fidelity A5 cd player and A5 intergrated amp, I have it
bi-wired to a pair of Acoustic Energy AE120 speakers (tri-wireable), my
question is this:-
My speakers are three way, so at the moment I have the MF and HF bridged
together & the LF is seperate, is this correct? Or I should I have the MF
AND LF bridged together & the HF seperate? I'm using Chord Chorus
interconnects and Chord Oddessy bi-wire speaker cable.
I like a mellow Jazz/soul/funk & detail etc not a lot of gutsy rock/bass & I
was just wondering if I had the config correct.

Thanks.

TBH I'm not sure what meaning "correct" would have in this context. :-)

Or I should I have the MF AND LF bridged together & the HF seperate?

Or simply link the MF + LF + HF together.

You can approach this in three ways:

1) Try different arrangements and if you think they sound different, choose
the one you prefer. If there are audible differences, it will be your
preference that determines what is "correct" for you, not the opinions of
others who may use different systems in a different room acoustic, etc.

2) Note that controlled listening tests have never (so far as I know) shown
any reliably audible differences due to bi-wiring, and engineering analysis
implies that any differences will be in the range from slight to imaginary.
[1] Thus simply use what you have and save bother.

3) Check with the speaker manufacturers to see if they have any engineering
reason for specifying a particular arrangement. If they do, consider that.

My vote would be for (2), but its your money and your ears... ;-

Slainte,

[1] If you use unusually inappropriate cable/equipment this might not be
the case. But in such cases the way to deal with the problem would be to
use more appropriate cables, etc. This isn't a matter of expensive or
fancy, just things like ensuring the cables don't have excessive
resistance, etc.

Totally agree. I think Jim is being kind, I would put the differences as
somewhere between imaginary and non-existent, once you do the sums.

Agreed. But still the OP might like to do the experiment, and decide for
himself. The subject is covered in an objective way in the book:
AUDIO REALITY by Bruce Rozenblit. pp 42-43.

Number 1 is correct, as only you with your equipment, cables, room and
furniture can LISTEN to the results. Plenty of sums are done by speaker
manufacturers, to make sure their product is technically brilliant, yet get
them into a room and they will sound anything from horrible to superb.

Same with interconnects and cables - use whatever sounds right to you. Some
people prefer the sums, some prefer the sound - it's a personal thing.

I've yet to see a product that didn't work properly when the sums were
done correctly, rigorously, and applying the rules. That's not to say
that an intuitive designer can't get a good sound without doing the
sums, what I'm saying is if you then analyse such a design, you will
find that the sums come out right as well.

What about the perfect speaker - a point source with a flat frequency response?
It will sound perfect if your room has no walls or floor.
If you design the perfect speaker for your room, it may not work well in mine.

I doubt you'll find anyone who would argue with that. Room/speaker

Alas, the snag in this context is that if there is a problem with the room
acoustics and its interaction with the speaker radiation patterns, then the
sensible way to deal with this is to alter the room acoustics, and/or
speaker radiation pattern - or the speaker/listening positions. Changing
the cabling is unlikely to have any effect - unless some of the cable
involved have extraordinarily inappropriate characteristics.

Same with interconnects and cables - use whatever sounds right to you.

For me the situation here is, alas, as in so many other areas of audio.
That people say things in reviews, etc, but none of them seem to have ever
been able to show any reliable basis for what they say. I know of no test
on 'bi wiring' that:

1) Ensured those listening had only the sounds produced to go on.

2) Repeated the test enough times, and with a protocol, that allows anyone
to assess the reliability of the reported results.

3) Used a protocol to exclude obvious uncontrolled factors like differences
in volume level.

...and which then gave results that supported the idea that anyone could
tell bi wiring from just using single wiring.

Slainte,

Jim

Years ago I read that one should disconnect everything periodically, clean
all the contacts and re-assemble. Did it. Everything sounded better. Now,
many years later I'm convinced that its psychological. Do it now. Play a
couple of tracks. Unplug your speakers and CD player. Re-connect and I bet
you think it sounds better. Works every time.
Re-wire your speakers any way you like. It will sound better when you have
them wired the way YOU think is right.
