Electrostatic headphone amplifiers are specialized devices designed to drive electrostatic headphones, which require high voltage to operate. Unlike traditional dynamic headphones, electrostatic models use a thin diaphragm suspended between two charged plates, producing sound through electrostatic forces. This design allows for greater accuracy and detail in audio reproduction. These amplifiers convert standard audio signals into high-voltage signals suitable for electrostatic headphones. They typically feature a high-frequency response and low distortion, enhancing the listening experience. Due to their unique requirements, electrostatic headphone amplifiers are often more complex and expensive than standard headphone amplifiers.
