Thus is controversial topic and I have heard all sorts of statements. What seems to be consistent at its base (I'm going to ignore brand names and technology to keep this less controversial) is that length of cable and Guage of cable matter. I dont have any hard numbers to contribute but for longer distances let's say 25ft the wire Guage should be higher ie 12AWG. I dont have a sense of low distance and what Guage you can get away with. Theoretically if its a 3ft run the Guage shouldn't matter that much. In audiophile land however I'm sure everything matters and so opinions will be hot on this.
I keep it really simple and go with monoprice 12awg. I buy terminal plugs and make my own lengths. This might cost you $70-80 or less to make a 100ft run if you chose. Once you get into branding and technologies however the arguments explode. I do know people with monos will argue for shortest length possible as one of the advantages is to be able to place your monoblock right next to the speaker. Ultimately if someone is building a system it seems most prudent to spend the money on the best components and treat wire as the final thought to save up on if one so chose. Otherwise 12 awg from any brand with your own terminal plugs is great.
