Nope i didnt , I didnt even know i had 2 type of different wires . All i knew i had Monsterwire on each side . It was truely driving me mad that i couldn't get my setup to sound right in the middle , the sweetspot was off center . I run my speakers , 3 feet from back wall and 2 1/2 from the side wall all equal , for optimal sweetspot and for the C9 .
Im not sure what they do to that XP wire .
Look @ my bedroom setup , it was driving me nuts , my equipment is not the best , but its better than the norm and now its sounds great , i love that SP3 Tube ( again TY Audioholics , you guys made my a very happy man ) amp are so much smoother on the treble and midbass , you guys @ Audioholics know how good these SP3 sound
