Acoustic Zen is an American company that has never belonged to the group of the most recognized cable manufacturers such as Cardas, Audioquest, Nordost and Tara Labs, but its products are well-perceived by audiophiles because of the sonic qualities and conductors used inside them. The brand was founded by Robert Lee, who previously created Harmonic Technology cables. It's no wonder that the products of both brands combine more than just the name of the founder. There's a similar philosophy and materials, with special regard to the metal of which the conductors are made. Americans were among the first who began to use mono-crystal alloys. Methods of obtaining wires with long crystals are different, but the idea is quite simple - the less microscopic barriers in the conductor, the clearer and less distorted signal.
