Electrostatic headphone amps are designed specifically for the high-voltage requirements of driving electrostatic headphones, which makes them perfect candidates to use vacuum tubes.
The HeadAmp Blue Hawaii SE is world-renowned as the best amplifier for STAX electrostatic headphones and uses a hybrid circuit of tube and solid-state components to achieve its powerful sound.
HeadAmp also offers all STAX amplifiers, sometimes called drivers or energizers, including tube, solid-state, and the new portable SRM-D10 mk2.
