HIFIMAN Shangri La Sr Amplifier

Description

Have you ever wondered how to achieve the quality sound and soundstage of a component system and speakers without filling up several hundred square feet of space? Electrostatic headphones offer this experience.

Electrostatic headphones are quasi active “earspeakers” and require a constant bias voltage on their diaphragm. This requires a dedicated amplifier, supplying not merely the music signal but the standing voltage as well. The Shangri La Sr. pairs uniquely designed, full-range electrostatic earspeakers with a tubed amplifier designed to drive them.

The amps enclosure is constructed of aviation-grade aluminum alloy and topped with a tempered glass panel. It incorporates 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.

There is a rear-panel switch which allows 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.

This listing is for the amplifier only; we can also provide the head-phones and amplifier as a set.
