Bi-wire: is it worth it?

Per the above poster...
"Keep in mind that a vast majority of speakers "can be bi-wired." IMHO, very few have actually been designed for this, and for most of them, it is just "audio fashion."

This is very true. And then, there are many well accepted
speaker manufacturers that do not even bother with bi-wiring/bi-amping by providing only one pair of binding posts - Vienna Acoustics, Dynaudio, Sonus Faber, etc.

As a Vienna owner, I sure am glad they have given me one less thing to obsess over so I can just sit back and enjoy the music.

Biwire is basically doubling up on the wire Gauge. If you notice a difference you would have most likely noticed a difference by just getting thicker wires. Think about it, it's now twice as much wire to conduct that signal. I really believe this is where the benefits truly come from.

I think the results also vary with different speakers and different wire. I would at least recommend that your jumpers be the same as your main cable.

There is an interaction between speakers by "Back EMF" generated voltage. Bi-wiring separates speakers by inductive reactance of the wires' and amp's output impedance divider. It works for some speakers more than for the others. I think it depends on xover design.

Elegal....I've heard the system bettered every time...sometimes dramatically, sometimes incrementally. In my experience, if the speakers were designed with bi-wire in mind (separate low and high sections ....2 (or more) input connections on the speaker) there is a very worthwhile improvement
