AUNE BU2 LDAC Bluetooth Balanced DAC Headphone Amplifier

Features

Mastertape-Level Decoding with Balanced Bluetooth

The BU2, part of the aune B-series, offers a new generation of DAC with a headphone amp, powered by a classic B1 single-to-dual positive-and-negative voltage power supply. Its compact body contains dual DAC chips and four amps, all designed for high-quality sound.

Transform Your Phone into a HiFi Player

Want a “DAP” experience? Simply connect your smartphone to the BU2 via USB, and it becomes a mastertape-level music player. Whether streaming from Apple Music or Kuke, your phone's music library becomes a HiFi experience on the go.

High-Quality Bluetooth Audio

Connect your smartphone, tablet, or computer to the BU2 via Bluetooth and enjoy high-quality wireless sound. With support for SBC, AAC, aptX, and aptX HD protocols, and special tuning, the Bluetooth audio performance is excellent.

Mastertape-Level Decoding via Computer

The BU2 can also be connected to a PC or MacBook, offering 32-bit/768k DSD512 mastertape-level decoding, delivering vivid, detailed sound presentation on your computer.

Dual DAC Chips and Four Independent Amps

Featuring dual ES9318 DAC chips in parallel, combined with four independent amps and the low-ripple positive-and-negative pump power circuit of the classic B1, the BU2 brings out the best in your earphones, offering excellent sound quality.

Clock Synchronization Technology

With two low-jitter 45M/49M oscillators synchronized with the DAC chips via the USB chip, the BU2 delivers a natural and refined sound.

One "Knob" to Control Everything

The single knob on the BU2 acts as both a button and control, allowing you to manage all settings and features with ease, providing a streamlined and simple user experience.

R2R Volume Technology for Enhanced Audio Performance

Featuring R2R volume technology, the BU2 uses electronic switches and an R2R ladder network for precise control at low volume. This results in better signal-to-noise ratio (SNR) and uncompressed dynamic range, preserving the detail in your music.

Excellent Specifications for Vivid Reproduction

Through careful design and multiple rounds of optimization, the BU2 achieves ultra-low noise (3.16uV) and THD+N (0.000145%). These excellent specs contribute to its vivid, high-fidelity sound reproduction.

Aesthetic Tuning

The tuning of the BU2 is based on real instrument sounds and musical references, delivering a natural, musical sound signature that enhances the listening experience.
