I'm running 10 gauge Monster Z-Series cable to my mains and center channel, and regular 16 gauge monster to my four surrounds. Now I am running the surrounds at quite some distance, and heres the question... If I were to get some Home Depot 10 gauge or 12 gauge cable would it maybe alter the sound a bit to warrant me NOT getting it?!?! Do you guys generally stick with one brand of cable or do you care?! I think the 16 gauge holds up with my back runs of 50 feet(after hidden and around objects, etc) still sound fine, maybe I'm missing something. Basically I'd like to get 12 gauge or something for the surrounds but don't want to pay a fortune because of the lengths! I'll take all the feedback you guys got!! Thanks.
