Description

Based on the B.dac one, the B.dpr one is equipped with an additional analog pre-amplification stage. Aiming at reproducing music as faithfully as possible with all its presence, naturalness and dynamics, the B.dpr one incorporates the main technological innovations introduced in the reference series.

Like our reference converters, the B.dpr one incorporates our patented SJR “Source Jitter Removal” technology for optimal conversion quality, regardless of the source. The preamplifier section features a 100% balanced analog volume control stage. It is built using discrete resistor networks switched by relays, preserving the signal integrity.

Design

Just like all B.audio electronics, the B.dpr one is elegantly and sleekly designed, with no visible screws. The CNC machined aluminium front panel features a rotary knob mounted on high quality ball bearings.

Remote control

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

ANALOG INPUTS OPTION

The B.dpr one can be turned into a real preamp when 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.
