Premium headphone amplifier
With the A 20 you will rediscover your dynamic headphones.
This new headphone amplifier from beyerdynamic is perfect for all headphone
applications and provides dual outputs for shared listening with a partner.
The circuit of the A20 is designed based on our legendary A 1 reference
headphone amplifier. The discrete output stage provides plenty of power even for
high-impedance headphones while the dynamic, open and precise sound sets the
A 20 apart from what can be found in the normal output stages of regular
amplifiers or receivers. This is confirmed by its first-class circuitry and
excellent technical specifications that provide a balanced sound for long
periods of comfortable listening.
High build-quality and nice looks
Made of brushed aluminum, the housing of the A 20 is especially solid and
resonance-free. Due to the innovative chassis design, no screws are visible on
the external surfaces. Equipped with an original ALPS potentiometer for variable
volume control, a knob turned from solid aluminum completes the attractive yet
robust look of this amplifier.
Simple and Flexible
With a high-gain RCA input, the A 20 works easily with most sources. The input
signal can be looped through and is entirely free from signal-loss thanks to the
hard-wired RCA output. Due to the built-in power supply, which is connected via
a detachable power cord (supplied), no external power supply is needed avoiding
disturbing background noise. Thanks to the dual headphone jacks on the front,
two people can listen to the A 20 together without an adapter cable.
