Alpha DAC Reference Series 3

The Alpha DAC Reference Series 3 contains breakthrough technology that redefines the potential of digital audio quality. Experienced industry listeners who have heard the Alpha DAC Reference Series 3 are unanimous in their praise, saying that the Reference Series 3 clearly outperforms any other DAC they have heard, including those with six figure retail prices, and even the much admired DAC portion of the Pacific Microsonics Model 2 studio ADC/DAC. In addition to its unprecedented PCM audio quality, the Alpha DAC Reference Series 3 also features MQA Rendering of unequaled audio quality.

Manufacturing each Alpha DAC Reference Series 3 to its full performance potential required development of a new hyper-accurate test and alignment procedure that is unique in the industry. This new test and alignment procedure allows extremely precise and repeatable production of the Alpha DAC Reference Series 3.

The original Alpha DAC Reference Series was a breakthrough product that reduced noise, particularly in the time domain, to levels significantly lower than any audio D to A converter previously available. The result was an immediacy and presence of music reproduction that was closer to the microphone feed than ever before. The unprecedented resolution of the original Alpha DAC Reference Series allowed and demanded further development and perfection of digital algorithms and analog circuitry that otherwise would not have been possible.

Now, the unmatched time domain resolution, low noise digital processing and highly accurate analog circuitry of the Berkeley Audio Design Alpha DAC Reference Series 3 combine to provide unprecedented audio quality with all PCM and MQA recordings.
