eyerdynamic A20 Review. The Beyerdynamic A20 is a small desktop headphone amp with dual 1/4″ outputs and comfortably handles 600ohm headphones.

Description

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.

SUPERIOR SOUND :

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.
