Rare NOS Genuine Western Electric/AIW 12 awg tinned copper. After many A/B comparisons (hard to digest) but this tinned wire beat out many sought after cables. These work magic with tube amplifiers. Very analog sounding. After 75-100 hours of burn in, these cables settle down and draw you into the music. See Jeff's place for reviews. Available with tinned 99.99% spades imported from Japan or NOS gold plated banana plugs I have been making quality handcrafted cables since 2000.
