X7s Class-A Balance Output Headphone

Aune X7s is a pure Class-A headphone amplifier that meets the most demanding requirements, it´s also a mini high-end desktop amplifier that can drive most of headphones and earphones.

Latest Hi-Fi desktop headphone amplifier from the same designer who designed Aune´s classic Panda and B1 headphone amplifier.

Compact Size
Slightly larger than the CD Disc, X7s´ flexibility apply to diverse listening environment as study, bedroom or office.

Equipped wit 8 pcs power transistors that split into 4 groups for true balance output, along with +- 15 V 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.

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 soundstage and warm sound character.

Excellent Measurements Results
Frequency response: 20 - 200K +-0.3dB, noise: 3µV, THD+N 0,00013% --- truly dark background.


Sound Tuning
The tuning is based on real instrument sounds and musical content referencing, resulting in a signature that is natural and full of musicality. Various renowned headphones were used in listening tests, such as T1, HD650, TK701, IE80, IE800, HD800, HD600, DT880, K240.

With three gears off gain adjust, X7s can drive most of headphones and earphones on the market.

Balance / Single -Ended Output
Four independent sub-circuits constitute the balance output that provides more realistic sound performance, two output terminals with two kinds of music style.

X7s trial products were well received by hundreds of people at the audio Fair.
