The Jade II is a technologically superior electrostatic headphone that can be purchased alone or as part of a full system with an outboard amplifier. Inspired by Dr. Fang's groundbreaking work on the Shangri-La systems this elegant system brings Electrostatic performance to unheard of value price. The Jade II Headphone is based on the Shangri-La Jr and has amazing transparency and detail. The Jade II Amplifier was custom designed from the ground up to optimally power the Jade. This system will blow your mind! The Jade II epitomizes electrostatic speed and performance. A low-distortion nanotech driver measuring less than 0.001mm couples near zero distortion with lightning-fast response and a nano-particle coated diaphragm that provides an extremely high-frequency response. Nano particle-coated diaphragms provide extended high-frequency response, revealing every last detail of well-recorded music. The combination of lightweight aluminum alloy construction, padded earcups, and a hybrid headband design ensures a comfortable fit, even for extended periods of time. The matching Jade II amplifier boasts analog performance from an all-solid-state design. Sleek and compact, the amplifier is equally at home in a rack, on a desktop, or nightstand – anywhere listeners prefer to enjoy their favorite music.
