B.dpr

DAC / PREAMPLIFIER

Enhanced version of the B.dac, the B.dpr integrates an additional 100% analog pre-amplification stage built with components of the highest quality. Digital losses are by construction non-existent, and the conversion circuits are used at their optimal operating point.

The B.dpr can be fitted with additional balanced and coaxial analogue inputs, turning it into a true preamplifier.

Full elimination of source jitter

The B.dpr features our patented SJR “Source Jitter Removal” technology which provides the best possible D/A conversion, from every source, by fully eliminating all imput jitter without the need of external clock link. The pre-amplification stage is done by a relay-driven resitor network that avoids any interference on the signal.

Design

Reflecting its exclusivity the B.dpr relies on a modern and sleek design featuring a machined aluminium front panel with integrated ball-bearing mounted rotary knobs.

Remote control

Each B.dpr comes with a custom-made remote control made of massive aluminium.

ANALOG INPUTS OPTION

The B.dpr can be fitted with an analog input board featuring two unbalanced inputs (RCA) and one balanced input (XLR). Thanks to the analog volume control stage, the signals coming from these inputs are processed completely in the analog domain.
