Aune X7S Class A Balanced Headphone Amplifier
The Aune X7S Class A Balanced Headphone Amplifier is the latest Hi-Fi desktop headphone amplifier from the same designer who designed Aune’s classic Panda and B1 headphone amplifier.
Reviews
“The X7s manages to do the one thing it’s designed to do very well indeed.
It combines excellent build quality with a refined, immersive, and neutral sound that offers just the right amount of richness and smoothness. The music always comes from a dark, ultra-quiet place thanks to that impeccable noise floor. It does all this while still staying mostly true to the information being fed to it by the source. It’s a paragon of both subtlety and dynamic musical power. At the price, it’s almost a no-brainer, especially considering the fact that it also supports ‘phones with balanced cables.” WitchDoctor
“Which leads me to the conclusion that the X7s is a powerful, capable amp for headphones of most designs and impedance ratings. That its design allows for balanced output is a boon, especially at its price.” Headfonia.com
Features
- Puristic Class-A headphone amplifier
- Balanced / unbalanced output
- 3 modes for different Headphones
- 8 power transistors in 4 groups
- Balanced sound and rich performance
Compact size
Slightly larger than CD Disc, X7s’s flexibility apply to diverse listening environment as study/bedroom/office.
Powerful
Equipped with 8 pcs power transistors that split into 4 groups for true balance output, along with ±15V regulated power supply result in a powerful driving ability.
Class A is also named as A class.
Two pcs of (or two groups of) crystal tubes of class A amplifier output stage are always in conductive state, that is to say, no matter whether there is input signal or not, they would keep conducting current all the time and make these two currents equal to peak value of AC power. At this time AC flows into load under condition of its large signal. Because of super-low infidelity of its open-loop, it is regarded as the most idealistic amplifying design of sound.
Class A has merits of fullness and clearness in sound and makes triode work within linear area forever, so infidelity hardly happen to class A. It gives a very good sensitivity of listening, especially its small signal, which sounds clear, detailed and rich.
Specifications
CLASS-A Function
- X7s was set in Class-A mode at 38mA static current of each output transistor, it results in a full bodied, wide sound-stage and warm sound character.
