The Alpha DAC Reference Series embodies everything Berkley knows about digital to analog conversion taken to an unprecedented level. The level brings an intimacy and presence of music reproduction that is simply real. The Reference Series was designed before it was even possible to build. 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. A high output metal IR remote control with direct input source selection is provided with the Reference Series. The JRiver Media Center software application is included in the price of the Alpha DAC Reference Series and either Windows OS or Mac OS versions are available.
