B.audio – B.dac EX DAC / Streamer / Server

Saint-Hippolyte, France | 2021 – The B.dac EX adds streaming and acoustic correction functionalities to the B.dac, our reference D/A converter. These include a network input, 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.

Its perfect balance and absence of coloration allow the B.dac EX to be integrated into any existing audio system. The recordings are sublimated, benefiting from an increased finesse no matter the musical style.

Full elimination of source jitter

The B.dac EX incorporates our patented SJR “Source Jitter Removal” technology. This unique process totally eliminates the temporal inaccuracies that are inherent to digital signal transmission. It provides the best possible D/A conversion, from every source.

Design

Reflecting its exclusivity the B.dac EX relies on a modern and sleek design. The machined aluminium front panel integrates high quality ball-bearing mounted rotary knobs.

Power supply

The B.dac EX features two distinct toroidal transformers: one designated for the digital domain, and another for the analog domain.

To prevent any risk of interference, there is one dedicated regulation per stage (DSP, clock, DAC, output stages, DC servo, etc.)

Upsampling

Carefully designed upsampling filters are a must have on any high performance DAC.
The B.dac EX makes use of a custom designed convolution engine implemented in a built-in DSP dedicated to this task. This permits to implement an in-house developed linear phase filter with reduced pre-ringing artifacts, preserving the transient response.

Output stage

To keep the accuracy of the signal shape, low phase deviation filters are implemented. This results in preserving dynamics and micro-information.

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.
