Much cheaper to throw on a few microinches of gold or print 
directional arrows on the speaker zip cord than it is to actually add 
components or change the connector style.  After all, if it was good 
enough for RCA back in the 30s , it's good enough for today.  Think 
of all the great features: non-constant impedance, unbalanced, 
connects signal line BEFORE the ground, easily bent (but at least you 
can manually unbend it), and I'm sure there's others.  And, I KNOW 
that my stereo sounds better with the arrows on the speaker cables 
pointing from amplifier to speakers in the direction of net average 
power flow. (I've also taken the precaution of ensuring that the 
arrows are on the upper side for horizontal runs, and on the NORTH 
side for vertical runs.  I use a large plastic owl on the stereo 
cabinet as a true north reference, based on extensive research on TT 
archives.<grin>)
