Aune X7s Silver

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. 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. 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.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. The tuning is based on re
