I have owned, and in some cases still own, Synergistic Research, Audioquest, Tara Labs, Mapleshade, AntiCables, Van den Hul and (yikes) Monster speaker cables.
And for under $30 I just bought from Blue Jeans Cable Co. 16 feet of Belden 12-gauge 5000UE and 4 pair of gold plated, compression style banana plugs. I cut the wire in half and installed the plugs, installed the shrink tubing, and then hooked them up to my speakers and to my amp in my system paying no attention to "directionality."
These speaker cables sound AS GOOD as any I have owned or listened to previously!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! No break in needed.
