BerkeleyAudioDesign의 전신인 퍼시픽 마이크로소닉스는 HDCD를 개발한 업체로, 프로용 A/D(Analog-to-Digital)컨버터와 마스터링 스튜디오에서 사용하는 HDCD 인코더를 만들었으며 프로용 장비로는 최고의 위치에 있었던 디지털기술력에서는 전세계최고의 회사였습니다..
이회사의 창립자이자 엔지니어였던 마이클 리터(Michael Ritter)가 여러가지 사정으로 인해 새롭게 창립한 회사가 버클리오디오이며
이회사가 가지고있는 세계최고수준의 디지털 전문기술과 초하이엔드 측정장비($100,000 정도의 테스트 장비, 얼라인먼트를 위한 $100,000 정도의 재생 기기)들을 가지고
음질에 악영향을 미치는 어떠한 것도 타협하지 않고 구현이 가능한 최고의 음질을 재생하는 제품을 만드는 데에 집중해서 탄생된 제품들이 버클리오디오디자인제품들입니다..

Product Highlights
- The Alpha DAC Series 2 employs new clocking and isolation technologies that provide enhanced imaging precision, timbrel purity and resolution.
- Unequaled interpolation technology up-samples 44.1kHz CD’s to provide almost 176.4kHz quality and produces superb fidelity at all sampling rates from 32kHz to 192kHz
- IR remote control of all functions including volume and balance allows direct connection to power amplifiers
- Advanced input signal jitter rejection
- Input selects AES, SPDIF1, SPDIF2 or Toslink inputs
- Lock LED indicates input signal lock
- HDCD LED indicates HDCD code detected
- Phase sets absolute phase
- Invert LED indicates absolute phase inverted
- 3 digit LED display of Stereo/L/R attenuation, Sampling Rate and Filter type
- ± controls set attenuation level and select Filter type
- Mode selects Stereo/L/R attenuation, Sampling Rate and Filter type display modes
- Dim selects multiple display brightness levels
