Berkeley Audio Design Alpha Dac Reference

This dac remains as one of the finest ever conceived and has an unparalleled reputation among owners and reviewers. They are rare to the used market and has an upgrade path. The presence and sonic reality of the Reference Series is the result of digital to analog conversion at a new level of accuracy made possible by tremendous electrical and mechanical noise isolation coupled with extreme time domain stability. Ceramic aerospace circuit board materials are used in all critical areas and the enclosure is carefully engineered to minimize electrical noise and maximize mechanical and thermal stability. The Reference Series weighs 30 pounds and the entire enclosure is precision machined from solid billet 6061-T6 aluminum alloy.
A new high output metal IR remote control with direct input source selection is provided with the Reference Series. Careful consideration was also given to providing the highest possible fidelity reproduction of DSD files by the Alpha DAC Reference Series. 99+% of modern DAC’s, including the Alpha DAC Reference Series, use multi-bit D/A converters because they provide better performance than 1-bit converters – even DAC’s who advertise “native” DSD compatibility. So, at some point, the 1-bit DSD stream must be converted to multi-bit for all of those DAC’s. Input sampling rate: 32kHz to 192kHz / 24-bit Ultra low phase noise Precision Clocking at 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz and 192kHz sampling rates ± 100 ppm Digital Inputs: AES - XLR, 110Ω; SPDIF1 - BNC, 75Ω; SPDIF2 - BNC, 75Ω; TOSLINK - Toslink optical connector Dimensions: HxWxD 3.5" x 17.5" x 12.5", 30 lbs.
