If someone claims power cables do not make a difference, they either don't have the hearing and/or the equipment to discern a difference. Basically saying...well, I can't hear anything different, therefore no on else can.
As to the generic cables supplied by many equipment manufacturers, they figure that the consumer will likely supply their own cable, so why include a fancy cable that would increase the cost?
With that being said, I like cables from Audio Envy, Ice Age Audio and Veritas Audio.
