Speaker cable length for L/R channels critical?

Regarding that man is not equipt to ´hear´ if L/R speakercables are of different lenght with potential phase and coloration errors - It was a fact a few years ago that we couldn´t hear much over 20Khz as well.

Speakers and sound reproduction mediums has evolved a bit based on what we can not ´hear´.

Art: If a cable colors the sound, then it is typically true that the longer it is, the more it will color the sound. (The exception: if what's coloring the sound is the circuitry within a network box, then cable length doesn't matter.) Whether cables *should* color the sound is a philosophical question, with no answer. Some audiophiles try to avoid such cables; for them, minor differences in length do not matter.

M: It is still a fact that we can't hear much above 20kHz. No amount of audio technology is going to change that.

I have my left cable at 25ft. and my right one at 10ft.
I can't tell any difference.

It is likely that you wont hear any difference. I have heard shuch systems with different speaker cable lengths, and I could not tell the difference.

Pabelson - Yes, I know our ears capability. Explain how come man can tell difference between a tweeter rolling off at 22Khz and a tweeter rolling off at 33Khz, when we should not be able to.

All the music reproduction industry is barking up the wrong tree stretching up their equipment above 20Khz?

OTOH I think it would take very special conditions for anybody to hear difference in cable leghts. One could probably sit very satisfied with such a sollution if other will not work.
I, on the other hand knowing that there is a mismatch/phase/coloration problem ( how ever tiny ) in my gear, would not accept that. But that´s me. Or as I thought the audiophile ´must-be-perfect-sickness´ ; )
