The H.E. Mark II is a dramatic step forward from the H.E.. Closer to the original Kaplan GS, the new H.E. II is a music lover's cord. The cord is a 3 conductor, 10 awg stranded copper cable that can handle very high current, yet remains flexible. Kaplan pays special attention to damping mechanical vibrations, with each conductor damped, the spacing material between conductors providing additional damping, and the outer jacket offering a 3rd layer of vibration damping. The overall sound is full bodied and warm, with a very transparent midrange and non fatiguing highs. This is not a cable that gives you the showroom "wow" factor, only to leave your ears tired after an hour. This is a cable that you can listen to for hours on end, and get completely lost in the music.
