Comparing Speaker Cables

No. But there also is no reason to bother comparing cables at all if you forget that fast what one sounded like. Either that or your cables are near identical. Either way, why bother?

Chuck didn't your mother ever tell you that if you don't have anything nice to say you shouldn't say anything at all?  In this case substitute constructive for nice.  And aren't you the one always saying everything matters?  And I have found that for me and my ears the only way to really figure out if something is better is to compare it as directly as possible to something else.  But hey, if you think your audio memory is that great I would be happy to have you come over and tell me which of the cables you think is better LOL.

I don’t know.  And when I did comparisons using a few songs there differences where clear. And there was song variations based on dynamic range of music and number of sounds within a bar. 

That is not a problem at all.

The design of the cable tells you all you need to know.

You always want your cables as short as possible. This is why we put mono amps behind the loudspeakers. This is most important with low impedance loudspeakers.

For full range speakers and subwoofers you also want heavy (low) gauge wire 12 gauge or lower with as low inductance as possible. Kimber Kable makes the best speaker wire although I do not care much for their interconnects. The real sonic difference to listen for is low bass performance.

Have fun!
