HiFiMAN Shangri-La Sr Electrostatic Amplifier and Headphones System

The HIFIMAN Shangri-La Sr System includes the Shangri-La Sr electrostatic headphones and a Shangri-La Sr electrostatic headphone amplifier. Featuring four vacuum tubes and durable aluminum alloy construction, the amplifier drives the headphones to produce a wide frequency response with low distortion. Designed for audiophiles, the Shangri-La Sr System offers balanced XLR and unbalanced RCA inputs for connection to a variety of signal sources such as media players, DACs, or phono preamps. HIFIMAN Shangri-La Sr Electrostatic Over-Ear Headphones The HIFIMAN Shangri-La Sr Electrostatic Over-Ear Headphones are open-back headphones designed to deliver detailed reproduction of dynamics and frequencies. When driven by the Shangri-La Sr headphone amplifier (available separately), the headphones yield a 7 Hz to 120 kHz frequency response via low-distortion Nanotech drivers. Acoustically transparent mesh grating and nanometer-thick dust cover protect the diaphragms without compromising sonic integrity. The combination of lightweight aluminum alloy construction, padded earcups, and a hybrid headband design ensures comfortable wearing even for extended periods of time. The 6.6' attached cable is terminated with a 5-pin headphone connector, which allows direct hookup to a compatible electrostatic headphone amplifier. HIFIMAN Shangri-La Sr Electrostatic Headphone Amplifier The HIFIMAN Shangri-La Sr Electrostatic Headphone Amplifier is designed to drive and complement Shangri-La Sr electrostatic headphones. Its enclosure—constructed of an aviation-grade aluminum alloy and topped with a tempered glass panel—is adorned with four 6SN7 vacuum tubes and four custom-made 300B tubes, which deliver warm tone and consistent output power for the Shangri-La Sr headphones (available separately). The volume level is controlled via a 24-step attenuator with 23 separate resistors. A rear-panel switch allows easy selection of either stereo input—balanced XLR 3-pin or unbalanced RCA coaxial. The selected input is fed through the internal circuitry and externally mounted tubes to the two 5-pin female headphone outputs, allowing simultaneous connection of two pairs of Shangri-La Sr headphones.
