This new headphone amplifier from beyerdynamic is perfect for all headphone applications and provides dual outputs for shared listening with a partner. The A20 headphone amplifier is used to operate up to two headphones with a nominal impedance from 30 to 600 ohms. The power amplifier, of a discrete design, and the combination of selected high-grade components inside the device allows even high-impedance hi-fi headphones to be driven flawlessly over the entire frequency range. Superior Sound The circuit of the A20 is designed based on beyerdynamic's legendary A1 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 A20 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 A20 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. The volume control adjusts the volume for both headphone outputs, which are connected in parallel. Its handy button is made of solid aluminum and hides a high-grade ALPS potentiometer with smooth volume values. Gold-plated RCA phono sockets on the rear are used to connect the audio source and allow a signal transmission without loss. The input is looped-through, which means audio signals that are present at the INPUT sockets are routed to the OUTPUT sockets, even when the device is switched off. Due to the hard-wired design there is no loss. The high-quality metal housing is made of brushed aluminum and protects against signal scattering and vibration. Simple and Flexible With a high-gain RCA input, the A20 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 A20 together without an adapter cable.
