Bryston BDA-2 DAC Black

Highly acclaimed Bryston BDA-2 DAC, black faceplate, excellent condition, no marks. 

The Bryston BDA-2 is a state-of-the-art
stereo DAC using fully discrete Class-A proprietary Bryston analog circuits,
two independent (analog and digital) linear power supplies and dual 32-bit AKM
DAC chips.  The BDA-2 also utilizes a new asynchronous USB input capable
of 192/24 bit resolution.  

The BDA-2 delivers inherent flexibility with an impressive array
of inputs for high resolution USB, COAX,OPTICAL, AES-EBU and BNC-equipped
digital devices. For audio outputs, the BDA-2 offers both balanced XLR as well
as unbalanced RCA stereo connectors on the rear panel. The BDA-2 is RS-232
software upgradable, making it the most user-friendly high performance USB DAC
on the market. “With more and more consumers relying on their computers as a
source of entertainment in the home, we felt it imperative to offer a DAC with
high performance USB inputs,” stated Bryston’s James Tanner. “Additionally, the
new 32-bit DAC chips deliver stunning resolution and detail. The BDA-2 was
built upon the award-winning BDA-1 architecture, which emphasized isolation,
low noise and imperceptibly low levels of distortion and Jitter,” Tanner
concluded.

Power
Supplies: The BDA-2 power supply employs two independent secondary
windings on the power transformer—one each for the digital and analog sections
of the device. In the BDA-2, each stage in the digital chain is also
independently regulated to prevent any unwanted interactions and to provide
rock solid power delivery for any up-sampling/over-sampling process.

AKM
32-bit DAC Chips: The BDA-2 incorporates dual AKM
32-bit DAC chips, some of the highest resolution available on the market today.

Jitter
Reduction: The input signal to the Bryston BDA-2 is re-clocked and
re-sampled with the highest precision oscillators to reduce any possibility of
jitter affecting the sound quality (jitter is a mis-timing of the data being moved
from point A to point B in any synchronous digital system). Additionally, the
BDA-2’s input receiver and sample rate converter have both been engineered to
further reduce jitter to levels too low to measure accurately even with the
best test equipment available.

Digital
Input Matching Devices: The BDA-2 employs high
quality impedance matching transformers providing the optimal interface to
virtually any incoming source under all sorts of signal conditions. Lesser
quality terminations may degrade the signal and could cause increased jitter.

Discrete
Class-A analog stage: The Bryston BDA-2’s analog circuits
are constructed of carefully sorted and selected discrete devices (individual
transistors, resistors, and capacitors) instead of the more commonly used integrated
circuits. The use of discrete devices has enabled Bryston to design a circuit
that exactly matches the needs of the BDA-2, resulting in superior sound
quality.

Ultimate Quality: Bryston
applies techniques and employs custom materials in our everyday manufacturing
of electronic equipment that are more typically utilized by the military and aerospace
industries. Such techniques ensure unit-to-unit consistency that is vastly
superior to mass production. Bryston’s adherence to the use of proprietary
parts, sophisticated construction, and refined testing techniques guarantee
superb performance and long-term
