Short Response

12 or 14 gauge is cheep

Its not the only wire/cable with a flat frequency response. In fact there are cables that cost hundreds of times as much with the same frequency response.

I have yet to purchase equipment that comes with speaker wire.

Long Response
Wire does make a difference. Expensive cables attenuate (lower the magnitude) of the signal at certain frequencies. So when someone says that they can here more details with a certain cable, all that cable is probably doing is attenuating the signal at lower frequency, then to compensate for this the consumer turns up the sound level a hair and high frequencies stick out(just like turning up the treble).

If you are like me and want the sound coming out of the speakers to sound as close as possile to being in the recording studio 14 gauge is the smallest gauge that produces no audible attenuation in the audio frequency range.
