Speaker Cables, One side longer- bad idea?

Hmmm...such fun, Bry.
But I believe the difference in electrical properties of the unequal cables will result in a different LOADING of the driving amplifier, thereby slightly changing the frequwncy response of each side, and THAT's what one could hear. Certainly would be the case with a high output impedence cable running hi-value cables assymmetrically, no?
I find it safer to run asymmetrical interconnects to monos, and then keep the speaker cables equal.
Another thought: imagine coiling the extra cable up and thus creating a huge inductor acting as a high pass into one side!
OTOH the effect is minimal if very low value cables (like Nordost, etc) are used, the output impedence of the amp is very low, and the ratio of L and R sides is small.
Good night.

A++ link, Bwhite! Thanks!

I also want to point everyone's attention onto damping factor explaination on the link provided by Bwhite and make your conclusion about different cable lengths.

And than read link about Equal length of the speaker cables.

I would not recommend to make such experiments with Transperent Audio cables and suggest to use some RadioShack wire or ZipWire.

Transparent Audio cables tended to have an out$tanding quality in terms of newtrality for inductance and capacity, but I wouldn't buy different lengths of Tran$parent Audio cables since I will not ever be able to sell them!

Another vast reason that most of power amplifier manufacturers strongly suggest in the manuals to use short equal runs of speaker cables to keep as close as possible to booked damping characteristics of amp.

Different length cables will not affect sound much. Speed of light (even at 90%) through cables less than about 1 mile long won't have any audible effect on phase between both channels.

it's really the inductance and impedance of the cable that will vary. It will have some effect on imaging (ie. will create slight smearing).
