What's the sonic advantage of bi-wiring

Theoretically, if you use the highest grade cable between your terminals as jumpers or if the crossover uses the best cable, Bi Wiring should not sound better. I've never seen 8 or 10 foot of cable sound better than a few inches of cable if equivelant cable is used throughout.

I stripped a small section of insulation off my speaker cable and ran it through to the second terminal figuring a consistent cable had to be not a bad thing?

the section between the two posts has the insulation.

In every situation where I've biwired, the sound quality improved. This was limited to using the same quality cables in both single wire and biwiring. I have never compared more expensive single wiring to lower priced biwiring. The typical benefit was an increase in midrange clarity.....similar to the difference when using good power conditioning.....the offending artifacts aren't that noticable until removed.

I think I first experimented with biwiring with Mission speakers in the mid 1980's.

Cable makers in general are not surprisingly behind bi-wiring...intersting to note that Wilson, a premium maker, doesnt see the benefits...which mirrors my experience...to each his own...

Asked another way, is there a disadvantage to bi-wireing speakers having the required binding posts.
