Thanks for your answers, i will email straight wire. I was talking about physical discription not sound.Ya,ll have a great day.
I purchased them at an autherized dealer a few years ago in new orleans ,they clearing out straight wire cables and i bought 4 pairs of interconnect, i was in a hurry and once i got home i noticed they were alittle different. Anyway i got my answer from a friend v2 has a thicker clear coating and the plugs are a little more heavy duty thanks again.
Man, by the title i thought this thread would be more general, and therefore, interesting. At least the OP found his answer. Like the joke says, after exhausting every conceivable way to tell the 2 horses apart, they found that the black one was 2 inches taller then the white one.
