B.dac one EX


Taking full advantage of all digital formats, the B.dac one EX uses the main technological refinements introduced in the reference series to deliver a natural and dynamic sound, rich in micro-information.

The B.dac one EX includes a network input giving access to streaming functionalities, as well as a USB slot for direct connection of storage media. Additionally, a DSP-based acoustic correction feature offers a wide range of possibilities for adjusting to the listening environment.


Streaming inputs are optimally interfaced with B.audio’s patented Source Jitter Removal (SJR) technology – a process that effectively eliminates 100% of the source jitter. Enabling the conversion circuitry to work optimally, the SJR provides unmatched digital-to-analog conversion quality regardless of the audio format used.

Network functionalities

The available features include:
– compatibility with protocols UPnP, MPD, LMS, NAA, Roon, Airplay, Spotify
– access to streaming services (Qobuz, Tidal, Spotify …) via compatible iOS and Android applications
– playback of various formats: PCM up to 384kHz / DXD / DoP / native DSD up to DSD 256
– integrated cloud / UPnP server (makes data stored on USB media accessible over the network)

Acoustic correction

The onboard DSP features parametric acoustic correction to help make the most of the room and speakers. In-house developed, this functionality is based on a 64-bit architecture. The overall gain is determined automatically without user intervention, which guarantees the absence of saturation regardless of the parameters used. These specific features preserve the signal quality, thereby ensuring an optimal result.

Remote control

Each B.dac one EX comes with a custom-made remote control made of massive aluminium.
