Aune BU1

The BU1 is a high quality portable DAC with headphone amplifier that purely focuses on sound quality. It supports up to 32bit/768k and DSD512 decoding; the amp is fully discrete, supports Apple/Android portable devices / portable music player connection; can be used in multiple scenarios. As a smartphone supports higher resolution music files and the online music libary grows larger, the portable Hi-Res DAC with headphone amplifier is becoming a must for phone HiFi. Connected tot he BU1, your cellphone will instatly become a Hi-Res music player. The BU1 supports connection with portable music players via USB. Try the special taste oft he fully discrete amp.
Connect the BU1 and your computer to decode PCM768 and DSD512. Then connect it to active speakers or headphones. A vivid music scene will be presented to you. Whatch concert videos and movies and play games on your phone with the BU1. Higher fidelity, more enjoyment.
The communication level SR series PCB leads to better high frequencies; the BI conductive film potentiometer leads to higher precision; th ultra-low-jitter oscillator leads to higher sound purity, the ceramic COG capacitor leads to lower disturtion. The BU1 continiues to use the classic B1s´positive and negative voltage regulator circuit. The circuit is ensured to stay in the best working condition. Thus the performance is maximized. The BU1 uses the amp circuit that is DC-feedback and fully discrete, resulting in the extended frequency and excellent transient. ON high-performance transistor applied. Better high frequencies.
The chasssis cut by CNC from a whole block of aluminium, the no-screw design, the brushed finish, the concentric knob/buttom.... BU1, a beuatiful work of art with excelllent details. Current/driving ability/size/performance are in proportion. In the compact body, the duration reaches 8 hours (measured at low gain; paired with the IE80).
