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.
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.
*Two 6.35 mm headphone outputs
*Elegant and solid all-metal housing
*Particularly open, transparent sound
*Also suitable for 600 Ohms headphones

反正要拿这货退t5p，dt880估计不行啊

看起来有点吃力。。。

感觉像是搞250欧的呢几个特斯拉。。

看起来挺小巧的

你看的懂那介绍吗？→_→

怎么感觉都等我吃螃蟹

坐等听感
