To be honest, I don't think the reason that bi-wiring might be better has
ever been explained to me in a way that I can take on board (with what
limited knowledge of physics and electricity that I have). Seems to me that
the effect of having the short between each run at the amp rather than the
speaker is so minimal that it's not worth bothering with. So far as I can
see, the only tangible difference is the addition of a small amount of
resistance in the circuit where the straps were on the backs of the
speakers. Like, 0.05 ohms, maybe.

If I'm missing something, I'd be interested to hear about it.

If it ain't broke, fix it until it is.

If you mean banana plugs, you need the size that fit. But why are you
obsessed with using banana plugs?


I find they're a cheapish, easy, reliable and convenient method of
termination, particularly if you change speakers from time to time.

Is safety your concern?

"Uncopyrightable"


One other thing, the VSX1016 has phase adjustment, so I 'think' that means
I do not have to have the same length for each of the front set,



** ROTFLMAO

That is real good one !!

Takes over 10,000 metres MORE cable on one side to be a mere cycle out at
20 kHz !!

Is your set-up bi-amped?


No, although I have wired it to the seperate speaker outlets. I only
used this setup because the Castles didn't come with the connection
bridges.

For a given cable, wiring them both in parallel is always better than
biwiring separately to the tweeter and woofer. Of course if the cables
are thick enough to start with, there will be no difference. I have
carried out a Spice analysis of this, which you can find he

http://81.174.169.10

It shows the net effect of biwired and parallel wired cables
(connected to each other at both ends instead of just at the amp end).
The parallel wiring wins.

If I go cheap is it better to bi-wire? most of the on-line reviews I
have read say bi-wiring is the best way to go, I am now very confuzzed.


Everybody doesn't have access to good advice such as you are receiving
here. The public are gullible when it comes to technology, and the
manufacturers know it.

No, it's nothing to do with resistance, it to do with the fact that each
speaker can be moving at different speeds and directions. From this
there is a chance that the woofer can send distortion up the cable and
interfere with the tweeter frequencies. You use a thick cable to the LF
to send raw power. The tweeter needs a cleaner signal, so you use a
thinner cable for that. By connecting the cables at source, and
separating them at the speaker, there is enough time to prevent the
interference.

On a proper bi-wirable speaker, you actually feed the crossover points
separately, so the signals don't actually mix. If you bridge the
connections, you turn it into an ordinary speaker.

I read an article about this in a pro magazine somewhere, but can't
remember the exact details now, but that was the general gist of it.

Of course whether you can hear the difference or not is a personal
preference.

You do know you just said all that out loud, don't you?

We can still hear you! And it still makes no sense.

Not in a Pro magazine you didn't. This stuff lies strictly in the
realm of the deluded amateur who doesn't understand the physics.

Of course whether you can hear the difference or not is a personal
preference.


I don't think you can "prefer" to hear a difference. You either do or
you don't.

I quite agree. How DO they get away with it?

No, you don't need to bi-wire. Period.




They get away with it because cables can sound different.

Does

help?

So far as I have been able to tell, bi-wiring has little or no effect in
the circumstances I expect to be normal in domestic situations.

I note that one of the cable manufactuers use the brand name "shark". Are
they trying to tell us something, I wonder?... :-)
