The best partner for your smartphone

As smartphones support increasingly high audio file resolutions and online music is becoming more and more abundant, the use of a Hi-Res DAC with headphone amplifier has become an essential requirement for anyone who wants to enjoy their music in high quality. Thus, connected to the BU1, your smartphone instantly becomes a Hi-Res audio player.

Enjoy your high resolution files

Simply connect the BU1 to your computer to be able to decode up to PCM 768kHz and DSD251. All you have to do is connect your computer to active speakers or headphones, and enjoy a lively sound scene and incredible clarity.

A rigorous selection of components

High quality SR PCBs for optimal signal transmission and high frequency reproduction, high precision BI film potentiometer, ultra low jitter clock for higher sound purity or ceramic COG capacitors for lower distortion level, the BU1 does not leave room for chance!

Discrete amplification stage

The BU1 uses a DC-feedback amplification circuit and is totally discreet. This architecture provides a better frequency response and an excellent transient response. For this purpose, high-performance ON transistors are integrated.

Beautiful housing

The chassis of the BU1 is machined with a CNC directly in an Aluminium block. Precisely cut, its design does not include any screws for a perfect result. With its brushed finish and beautiful, perfectly integrated buttons, the BU1 is not only robust, but also has a sublime aesthetic.

Outstanding balance control, long autonomy

Current, ability to accompany headphones, dimensions, performance, everything is balanced in this DAC / headphone amplifier. In addition, its 4000mAh battery ensures an extremely clean power supply and guarantees an excellent autonomy, up to 8 hours.

Excellent specifications, transparent rendering

The BU1 offers excellent technical specifications: a distortion of only 0.00076% and a noise level at 1.97µV, allowing deep bass and impressive richness to be reproduced.

In addition, the device has been calibrated using real instruments and numerous reference audio contents for reference, in order to provide both neutral and musical sound.
