These are the desirable things in a speaker wire/connectors:
Must have low resistance so as to not increase the output impedance of the amp. You get that by using better and thicker conductors. Copper is fantastic. So, the purer the copper, the better the conductance. Having said that, no need to be ridiculous either. 99.99% of the people wont be able to tell the difference between 99% pure copper
and 99.9999% pure copper. Not worth the extra which only a very sensitive measuring device can notice.
Lower capacitance. Higher capacitance will impede hi frequencies. But then again, you
will not notice it in a few nano farads.
Lower inductance. Do not coil your wire, run it straight. Increased inductance may affect the rise time of your signal due to an inductor resisting the rate of change of current thru it. Again, a few nano henries will not be noticed.
A perfectly good pure copper speaker wire of about 12 gauge can easily be bought for about $50. No need to spend any more, unless you want to run miles of it.
