Mark I know you're a good person, and I like nice audio gear as much as the
next guy but do the math:
Electricity travels in a perfect medium at the speed of light; through
copper wire it travels some fraction of that. The only specific references
I've found on the net suggest that a real-world figure would be something
on the order of a meter every 1/5,000,000 of a second. In other words,
200 nanoseconds per meter.
If you have two speaker cables -- one 3 meters long, and the other twice
as long, the phase error between the speakers would amount to 600 nanoseconds,
or just under 1 millionth of a second. Are you telling me you can hear
phase errors in the microsecond domain?
