DAC / PREAMPLIFIER

B.dpr EX

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 analogue preamp section of the B.dpr offers both balanced and coaxial inputs.

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 aluminum front panel with integrated ball-bearing mounted rotary knobs.

Analog Inputs

The B.dpr features 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.

Remote Control

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