Product Description

716014 A 20 Headphone Amplifier. Rediscover your dynamic headphones with the 716014 A 20 Headphone Amplifier, which is perfect for all headphone applications and provides dual outputs for shared listening. The circuit of the 716014 A 20 Headphone Amplifier is based on the legendary A 2 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 716014 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. Made of brushed aluminum, the housing of the 716014 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. With a high-gain RCA input, the 716014 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 716014 A 20 together without an adapter cable.

    A 20 Premium Headphone Amplifier

    Whether you’re sitting at your computer or relaxing in your living room, a good set of headphones requires a suitable partner in order to truly reach its ultimate sound potential. Using standard headphone outputs on PCs or CD players greatly reduces the quality of your acoustic experience. Users of high-quality headphones benefit from greatly increased dynamics and precision with a headphone amplifier.

    Optimised audio in a compact format

    The increase in sound quality is remarkable and even top-of-the-line headphones benefit from the advantages of the A 20. Thanks to its linear and low-distortion circuits, the user benefits from a significant increase in dynamics, openness and precision. The bass has noticeably more definition and substance, vocals and instruments sound more natural and have more spatial layering, the treble is less aggressive and has a more precise resolution.

    Professional technology for audiophiles

    Only high-quality materials and top components are used in the A 20, which ensures durability and provides the best possible sound quality. The A 20 has sufficient power reserves for simultaneous operation of two headphones with up to 600 ohms of impedance. It is perfectly able to handle high levels and dynamic peaks.

    First class and high quality

    Made from brushed aluminium, the A 20 housing is especially high-profile and resonance-free. Due to the innovative mechanical design, no screws are visible on the external surfaces. The original ALPS potentiometer for variable volume control is operated via a rotary knob made of solid aluminium. In short: an outstanding and durable amplifier.

    Simple and flexible

    The A20 comes with a RCA / phono input so it can be connected easily to any high-level source. The input signal is looped through with the result that audio signals at the Input jacks are forwarded entirely free from signal loss to the Output jacks even when the device is switched off. Thanks to the two headphone jacks on the front, two people can listen to music at the same time with the A 20.

    Customers are mixed about the sound quality of the av receiver. Some mention that it's really nice with a fullness of sound, and the passthrough audio is huge. They say that Stevie Wonder's bass songs are clear, deep, rich, and not cloudy. However, others say that it doesn't produce any better sound than their regular old phones jack, and that it sounds dead and lifeless.

    Great Amp, smallest of detail nuance

    Great Amp, smallest of detail nuance
    Honestly, as an amp that you'll probably never see or really stare at after setting it up other than to adjust the volume my one complaint is barely even noticeable. The button isn't centered. That's it. That is the only complaint I have.This thing fuels my dt-1990 pro and sends my ears to a heaven that I've only recently began to explore. I'm not an engineer, I just enjoy hearing everything that the engineers have produced for our enjoyment and this amp helps you get it.
