B.dpr EX

DAC / PREAMPLIFIER / STREAMER / SERVER

Enhanced version of the B.dac EX, 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 EX features analog, balanced and coaxial inputs allowing the connection of up to 3 additional analog sources.

Full elimination of source jitter

The B.dpr EX 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 EX relies on a modern and sleek design featuring a machined aluminium front panel with integrated ball-bearing mounted rotary knobs.

Network functionalities

The available features include:
– compatibility with protocols UPnP, MPD, LMS, NAA, Roon, Airplay, Spotify
– access to streaming services (Qobuz, Tidal, Spotify …) via compatible iOS and Android applications
– playback of various formats: PCM up to 384kHz / DXD / DoP / native DSD up to DSD 256
– integrated cloud / UPnP server (makes data stored on USB media accessible over the network)

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.

Acoustic correction

The onboard DSP features parametric acoustic correction to help make the most of the room and speakers. In-house developed, this functionality is based on a 64-bit architecture. The overall gain is determined automatically without user intervention, which guarantees the absence of saturation regardless of the parameters used. These specific features preserve the signal quality, thereby ensuring an optimal result.

Remote control

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