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.

From the manufacturer
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.

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.

It is a very nice looking amp, being well built and smart but understated. It has a good heft to it and appears solidly made. The only niggle with build quality was the volume knob appears to get more resistive as you turn it over 50%, it appears it is slightly off concentric, but it is a minor problem and doesn't detract from the use of the unit.
It drives all my headphones with ease.
Beyerdynamic DT880 600ohm,
Grado SR225e 32 Ohm,
Klipsch X11i 50 Ohm,
Sennheiser Momentum M2 over ears 18 Ohm,
Sennheiser HD579 50 Ohm,
Sennheiser HD650 300 Ohm.
(Ranked in order of best meshing with the A20 to my ears)
I have put about 20 hours on the Amp.
It pairs unbelievably well with the DT 880 600ohm's. It adds a lot of resolution and air to the headphones. The soundstage is improved and it adds weight and meat where its needed. Very musical and easy to listen to. The clarity is remarkable. The headphones become incredibly insightful. (The headphones could use a bit more of what I perceive as mid bass or meat, so I'd imagine the 770 or 990s would mesh even better). Vocals are clear, central in depth, slightly warm of neutral and very realistic on the 880s, but don't have that HD650 usual velvetyness and weight. Treble is extended to the point of being a smidge bright to my ears on some tracks, but wow, it is so resolving. It is a neutral amp, but musical, as I just want to keep listening to all my tracks and discovering new ones. Amazing with Jazz and classical, but a great all rounder. I'm running it from the RCA outs of an ASUS STX II and under 50% volume I could not detect any noise from the Soundcard. (I picked up noise from the computer over 50%, but that is not the amps fault).
It didn't mesh as well with the 650's and they sounded far less detailed after the 880's. The sensation reminded me of what cardboard sounds like in comparison to the clarity of the Beyers, and the 650s are some of my absolute favorite headphones, so I wouldn't recommend it as a good pairing with the Sennheisers, It doesn't flatter them compared to how it brings the 880's alive. The 650's sound full and lush and warm from the STX II headphone out on the 300 - 600 ohm setting, but not as warm from the A20, To me it highlighted the differences between the 880 and 650 sound.
All my other headphones sounded very similar to their original sound signatures. The HD 579s gained extension in the bass area but sounded "natural" in the other ranges. The Grados sounded a tiny bit warmer and really nice with a fullness of sound and closest to the 880s insightful sound. The A20 didn't really add any colouring to the music, it just amplified, which to me is the mark of a good neutral amp.
My guess is this amp will work well with most higher impedance headphones. I don't know how it will pair with the lower impedance beyers but I'd imagine it would work extremely well with the 250ohm versions as well.
If you own a set of Beyerdynamic DT range headphones especially the 600 ohm versions, I highly recommend trying this amplifier, it really pushes them to a new level. Would love to try the Amirons on this amp when the wallet allows, as I think the middle ground between the 650s mids and the 880s insight is where my my Audio Nirvana is hidden, but I'm really happy with the 880s on this amp in the interim. The A20 is a keeper.
I am stunned at the results.
The soundstage and definition with the A20 is as if the musicians are in my living room, to my left and right, and the center for the singer. Each note, each fingertip against a bongo, cajun, or cello, is clearly defined. The sound from the A20 is crystal clear and more defined than I thought possible. I did not think anything could sound better than the T1 coupled with the O2 until I heard this. The sound is stunning.
I am not an audiophile so I lack the audiophile's vocabulary; suffice to say, listening to Sgt. Pepper's has alerted me to sounds, notes instruments, and harmonies I did not know were on the album.
The London Philharmonic highs are clear and distinct, while Stevie Wonder's bass songs are clear, deep, rich, with no 'cloudy' or muddled sound. Alison Krauss' highs were perfect, while Dylan's low growl's were as if he, too, was in the living room giving a performance.
Amber Rubarth's album, "Sessions from the 17th Ward" must be heard through the A20 (with good headphones!) to see what it is like to quickly turn one's head to the left, thinking someone is there playing the bongo, while to the right, the cello plays.
It is in trusting the synergy of the company, the German manufacturing is still a thing of both beauty and structure. It is built like a tank and even its feel is quality. The T1's are the "Mercedes Benz" of headphones, with the same quality of artisanship here with their amp. A must buy for those who have invested in a good amp. Even at low volume, the separation and clarity is amazing.
It brings your well worn and used music library into new life.
Update:
I can't get over how much I love this amp with my DT880s! I've always been lukewarm on the sound but kept them because they are by far the most comfortable to wear all day. This amp really fills out the sound signature and has made them the favorite all-arounders in my arsenal. I wish I could give it 5 stars, but I think my criticism of the uselessness of the second phones jack stands.

No es una necesidad pero si eres amante del audio y quieres asegurarte que tus audifonos esten dando todo su potencial es buena compra...
avendolo inserito in uscita del mio Hi-fi ho fatto un po di prove tra l'uscita cuffie del mio amplificatore advance acoustic e A20. Non c'è paragone.
Con A 20 è tutt'altra musica, consiglio l'acquisto, provare per credere.
