What else to know about the BDA-1?

The Bryston BDA-1 is an external Stereo DAC (Digital to Analog Converter) using fully discrete Class-A proprietary Bryston analog circuits, two independent linear power supplies, and dual Crystal CS-4398 DAC chips. The BDA-1 features an impressive array of inputs for USB, COAX, OPTICAL, AES-EBU, and BNC equipped digital devices. For audio outputs, the BDA-1 offers both balanced XLR as well as unbalanced RCA stereo connectors on the rear panel. The BDA-1 is RS-232 software upgradeable via PC, Mac upgrades are not supported at this time. I have been informed by Bryston that there have not been any firmware upgrades for this model so that should not be an issue for Mac owners Bryston delivers superb sonic performance by re-sampling and re-clocking the digital input in order to reduce jitter. The result is a significant reduction in jitter (1/1000 of a nanosecond). But it isn't enough to just get the bits right; those bits have to be converted back into music with the same timing reference as when the music was first digitized. The input signal of the BDA-1 is re-clocked and re-sampled to reduce any possibility of jitter affecting the sound quality. Even the input receiver and the sample rate converter serve to further reduce jitter. The most critical part of the circuit design in the Bryston BDA-1 is the DAC's analog outputs, connected directly to a pair of proprietary Bryston Class A discrete operational amplifiers. Bryston hand assembles using only the finest components and individually tests every product they manufacture. There are 6 digital inputs, which are easily selected using a front panel switch.  \-

Brief History of Bryston

Founded in 1976 by the Lanois brothers (including Grammy award winner Daniel Lanois) and Bob Doidge, Grant Avenue Studio is a recording and mixing facility based in Hamilton, Ontario, Canada that also provides mastering and tape transfer services. The hallowed rooms within the stately converted early 1900's Edwardian home on Grant Avenue have seen numerous recording legends such as Gordon Lightfoot, Bruce Cockburn, Ian Thomas, U2, Johnny Cash, Los Lobos and countless others. Bob Doidge became sole owner of the studio in 1985 and touts Hamilton as a cultural gem just Southwest of Toronto on the shores of Lake Ontario.
