These will put most megabuck cables to shame. NOS Genuine Western Electric/AIW 12awg cloth/tinned copper. Twisted Pair for maximum noise rejection. These work magic with tube amplifiers. Very analog sounding. Terminated with NOS gold plated banana jacks. Also available in tinned or gold plated spades. Hard to believe but audiophiles sre replacing Cards Clear for these. See Jeff's place for reviews. I have been making quality audio cables since 2000.
