Headphone Amplifiers

Headphone preamps are audio components designed to amplify line-level audio signals for playback through headphones. They provide the appropriate gain and output control required to drive headphones accurately, ensuring stable performance and consistent sound levels. In hi-fi systems, headphone preamps are used either as dedicated listening components or as part of a larger preamplifier or DAC-based setup.

Headphone Preamps for Dedicated Listening Systems

Headphone preamps sit between an audio source and a headphone output, receiving an analogue signal from a DAC, preamplifier or other line-level source. Unlike speaker amplifiers, headphone preamps are designed for low-power, high-precision signal delivery, allowing accurate level control and stable performance across a wide range of headphone impedances. Headphone preamps commonly receive analogue audio from digital-to-analogue converters (DACs) or other line-level source components.

Some headphone preamps are designed as standalone units, while others combine additional functions such as digital-to-analogue conversion or preamplification. Selection depends on the source components being used and whether the headphone preamp is integrated into a wider hi-fi system or used as a dedicated listening component. In mixed systems, headphone preamps may be used alongside or integrated with an amplifier, providing a dedicated headphone output without affecting the main speaker signal path.
