The pure class A Aune X7S headphone amplifier with balanced output is the result of a long search after the nomadic headphone amplifier Aune B1 and the Aune Panda. It is the natural companion of the DAC Aune X1S 32bit 384Khz DSD SABRE ES9018K2M. This headphone amp entirely in class A is the synthesis of all the know-how of Aune Audio. It is specially designed for high-end high impedance headphones such as: Sennheiser HD650, IE800, HD800, Beyerdynamic (Tesla) T1, DT880, AKG K701, K240.

Its gain stage, which can be configured by "switch", allows a perfect impedance matching for both low and high impedance headphones. Its structure is based on 8 Class A polarized transistors divided into 4 groups designed with a true symmetrical stage for cross talk and remote, inaudible background noise. The European sound of the Aune X7S developed by an English team has body, a deep sound image with increased natural musical tracking, a true sound signature of headphones amplifiers in class A. The separate 15 V regulated low noise power supply provides the stability necessary for the Aune X7S to operate properly in class A. By its unique design the Aune X7S will be an ideal companion for the dematerialized digital player Aune X5.
