Speaker Wire length

ahem

300,000 km/sec

Dude, that was some quickness coming up with that figure!

hehe - boredom I suppose. Its just the speed of light in a vacuum. I'm sure its slower through a copper wire, depending on resistance and whatnot - as you stated. Then again - I'm sure not even the haughtiest audiophile could tell the difference.

However - What about different gauges of speaker wire going to a left and right speaker - could one tell the difference? lol

This question is one of the many points where "true audiophiles" will argue.  The same people who buy $300 platinum plated RCA  interconnect cables and run 4 gage speaker wires will tell you that the speaker leads need to be the exact same lentgh or you can introduce time alignment errors in your system.  And, in theory, they are correct.  But in actual practice I've never seen it make much difference unless the wire length is VERY gross (like one wire at 3 feet and the other at 300 feet.)  And then the milisecond time delay difference was not something one could hear, only something that could be measured with a scope.

Now that being said, I must admit that I, more out of fear, witch-craft and superstition than logic, always make my speaker wire runs the same length.  I guess knowing something is possible is enough to make me try and eliminate it when it only costs a few pennies to do so.
