• 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.

  • The Alpha USB is an asynchronous High Speed USB Audio 2.0 to digital audio interface designed to provide the highest possible audio quality from computer and music server audio sources.

    The Alpha USB has a USB Audio 2.0 Standard input and switch selected digital audio output signal type, either coaxial SPDIF using a BNC connector or balanced AES using an XLR connector. Sampling rates up to 192 kHz and word lengths up to 24 bit are supported.

    Great care was taken in the design of the Alpha USB to isolate the noisy computer/USB environment from the digital audio output. The USB receiver and processing are powered by the computer, while the output master clocks and line drivers are powered by a separate isolated linear power supply. There is no DC connection and also a high degree of capacitive and inductive isolation between the USB input and the digital audio output.

    Two key factors combine to achieve the excellent audio performance of the Alpha USB; the unprecedented degree of electrical isolation between the USB input connection and the digital audio output and the very low noise/low jitter performance of the individually tested audio output master clocks.
