..what really impressed me was the unique voicing. I can’t name another DAC which sings this enchanting and inviting but withholds the usual drawbacks of such sonic traits. That makes it into an enormously gratifying find, expert mood setter and liquid performer of the highest caliber..

Philosophy

RESEARCH

D/A conversion is the cornerstone of modern sound reproduction systems.

Resulting from more than 10 years of investigations and engineering, our unique SJR technology, standing for Source Jitter Removal, provides a direct line between digital and analog.

It guarantees an optimal conversion quality by fully eliminating source related jitter artifacts, form any source.

DESIGN

Reflecting their exclusivity, our devices rely on a modern design, featuring a CNC-machined aluminium front panel with integrated ball-bearing mounted rotary knobs.

Inspired by celestial gravity, the housing style stands out for the purity of its lines, letting aside any disturbing element.

Product design by Olivier Hess

LONGEVITY

Best sonic qualities are nothing if they fade in time.

All components are carefully selected to keep optimal characteristics over time. For instance, every chemical capacitor used in our products withstands a minimum of 5000h of operation at 105°C, which translates to more than 40 years of continuous operation in typical operating conditions.

All our products come with a 3 years warranty.

Technology

Source jitter removal patent

One common source of sound artifacts in digital to analog converters is due to the jitter present in the source signal.
To get rid of this phenomenon, we developed a unique technology called SJR “Source Jitter Removal” that can fully eliminate all input jitter, from any source (SPDIF, Toslink, AES/EBU, USB) without the need of external clock link.
Based on a clean clock generator fully decoupled from the source signal clock, it provides optimal timing for the D/A conversion, and thus removes the well-known digital harshness.

Power supply

Our D/A converters feature 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.)

Direct coupling

Even the best imaginable coupling capacitor will always perform worse than no capacitor at all. To allow direct-coupling operation without risking the presence of voltage offset at output, we developed a specific multi-pole DC servo. Completely separated from the audio signal path, it allows to do without any DC component that could affect the signal.

Upsampling

Carefully designed upsampling filters are a must have on any high performance DAC.
Our products make 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

Every DAC technology generates undesirable high frequencies, which have to be filtered out analogically. To keep the accuracy of the signal shape, low phase deviation filters are implemented. This results in preserving dynamics and micro-information.

About

B.audio is born in the wake of passion for music and high level engineering. It was founded by two brothers sharing the same philosophy: reproduce the music as naturally as possible, in the true spirit of High Fidelity.

B AUDIO has taken place in Mutzig (67) in an old brewery located 20min away from Strasbourg.

Our products are all hand made with the highest dedication. Every product is carefully tested and listened after being assembled.
