B. Audio B.dac one


Enquire now


Taking full advantage of all digital formats, the B.dac one 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 incorporates our patented SJR “Source Jitter Removal” technology. It provides optimal conversion quality, even from sources subject to a significant level of jitter, regardless of the input (USB, AES-EBU, SPDIF or TOSLINK optical).


Adopting the refined aesthetics typical of B.audio products, the B.dac one features a visually screwless enclosure, which includes a massive CNC machined aluminum front panel fitted with an OLED display housed in a glass window.

Power supplies

Like our reference models, the B.dac one has a dual power supply that separates the digital domain from the analog domain. The transformers are sized accordingly to ensure perfect operating stability.


The B.dac one uses a linear phase digital filtering system that has been optimized to prevent pre-echo phenomenon and guarantees an optimal transient response. This oversampling process is embedded in a DSP that employs in-house developed algorithms.

Output stage

The B.dac one features a 100% balanced analog output stage with low-phase deviation filters like our reference converters.
