Astell&Kern PA10 – Portable Class-A Headphone Amplifier for uncompromising analog sound

Analog sound perfection on the go

With the Astell&Kern PA10, Astell&Kern presents its first portable Class-A headphone amplifier, combining audiophile sound quality with maximum mobility. Designed for discerning music lovers, the PA10 complements digital audio players and other high-quality audio sources with the characteristic warmth, dynamics, and naturalness of a genuine Class-A amplifier.

Thanks to the exclusive TERATON ALPHA technology, individually adjustable gain, and three-stage current control, the PA10 delivers an exceptionally detailed and spatial sound experience – anywhere, anytime.

Genuine Class-A amplifier for natural sound

The Astell&Kern PA10 features a true Class-A amplifier circuit, renowned for its linear signal amplification and exceptionally natural sound.

Unlike conventional amplifiers, Class-A technology operates almost distortion-free, producing a warm, harmonic sound with impressive detail resolution. Vocals feel more authentic, instruments gain body, and the entire soundstage unfolds with extraordinary spatiality.

TERATON ALPHA – The audio technology from Astell&Kern

Inside the PA10 resides the exclusive TERATON ALPHA technology, which pools all of Astell&Kern's expertise in the field of high-end audio engineering.

Through intelligent power supply, effective noise reduction, optimized signal routing, and precise amplification, TERATON ALPHA guarantees particularly clean, dynamic, and unadulterated music reproduction – regardless of the audio source used.

Three-stage Class-A current control

A special feature of the PA10 is the three-stage current control, which allows the sound characteristics to be optimally adjusted to different headphones and in-ear monitors.

Depending on the selected setting, the operation of the Class-A amplifier changes, allowing for even more precise control over spatiality, dynamics, and sonic richness. At the same time, power consumption is efficiently regulated to ensure a long battery life.

Gain control for every headphone class

The PA10 features a switchable gain control (High Gain / Low Gain).

This allows the amplifier to be optimally matched to sensitive in-ear monitors as well as demanding high-end headphones. In balanced operation, the PA10 delivers an output voltage of up to 6.2 Vrms, ensuring superior power reserves and maximum sound quality.

Fully balanced 4.4 mm circuit design

Unlike many portable headphone amplifiers, the PA10 processes balanced signals without additional signal conversion.

The integrated 4.4 mm input and output enables lossless, balanced signal routing with particularly high dynamics, low noise floor, and excellent channel separation. In addition, standard 3.5 mm connections are available for maximum compatibility.

Crossfeed for natural headphone listening

The integrated Crossfeed mode ensures a more natural stereo image when listening to music via headphones.

By purposefully mixing the two channels, a more spatial soundstage is created that resembles listening via speakers while reducing listener fatigue during long sessions.

Compact design with up to 12 hours of battery life

Despite its powerful Class-A technology, the PA10 remains pleasantly compact and portable.

The integrated battery provides up to 12 hours of music playback, so you can enjoy the characteristic Astell&Kern sound on the go. Charging is conveniently performed via USB-C.

Iconic Astell&Kern design

The PA10 bears the unmistakable design signature of Astell&Kern.

The striking SLOPE design combines high-quality materials with ergonomic operation, making the amplifier an elegant companion for high-end digital audio players and mobile Hi-Fi systems.
