DIGITAL / ANALOG CONVERTER

B.dac

The B.dac is our reference D/A converter.

Its design is the result of a global reflection involving a search for perfection in the possible synergies between the best available components.

Its perfect balance and absence of coloration allow the B.dac 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 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 relies on a modern and sleek design. The machined aluminum front panel integrates high quality ball-bearing mounted rotary knobs.

Power Supply

The B.dac 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 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.

Remote Control

Each B.dac comes with a custom-made remote control made of massive aluminum.
