Why do you think Bi-Wiring improves the sound ?

I must say that I don't get the bi-wiring routine. It seems to me all that is
being accomplished is adding more connections (points of failure). If you have good speaker cable to begin with doubling it does virtually zero. The signal still has to go through the passive crossover with its inherent flaws.
The amp is still going to feel the back EMF of the woofers. Oh well. Some things should just remain mysterious to me.

@ieales " ^^^^ typical post of someone reading the title and inserting their 0¢.

'Good' speaker wire is meaningless. The cable is part of a system and $$$ is often sonically and measurably worse than ¢¢¢."

I've been called many things but "typical" is not one of them. A first!
I don't understand your second and third sentences quoted above. 
Please educate me. 

Lastly, in the spirit of banter, by "good" I mean that the owner of the rig
and cables thinks they are "good" and I don't see how that is meaningless.
