About the Stat

The Bottlehead Stat is a custom-made, fully assembled tube electrostatic headphone amplifier/energizer designed for electrostatic headphones. It uses a zero global feedback, class A circuit with a single input, balance control, and level control. The amp supports both 580V Stax Pro Bias and 230V Stax Normal (legacy) bias headphones, and Bottlehead notes compatibility with electrostatic headphones from Stax, Koss, Hifiman, and Nectar Sound. It is sold only as an assembled unit because of the high voltages inside the chassis. Bottlehead also describes the design as a two-stage differential amplifier per channel with C4S constant-current sources and a tube-rolling-friendly output stage.
