I have owned Harmonic Tech and Acoustic Zen. Mr. Lee was one of the founders of Harmonic Tech, and has moved on to form AZ. There are some sonic similarities but I opted for the Zen. Much better than the dark sounding Cardas. Another great cable is the Pure Note Epsilon. It is a very fast yet smooth sounding cable. You can only get Pure Note online, no dealers but you save many dollars. Right now I am trying to decide if I will return the Zen's or the Pure Note's. Both are great!
