About the Alpha (Series 1)

The Alpha DAC Series 1 by Berkeley Audio Design was released around 2008 with an It supports input sampling rates from 32kHz to 192kHz and 24-bit word length. The unit features multiple digital inputs including AES/EBU, SPDIF on BNC, Toslink, and Berkeley's proprietary BADA input. It offers balanced XLR and unbalanced RCA analog outputs with high output levels (6.15Vrms balanced). The DAC includes a digital volume control with 0.1dB steps and balance control, allowing it to function as a preamplifier when connected directly to power amplifiers. The front panel has a large alphanumeric display showing input sampling rate and status LEDs for input selection, signal lock, and HDCD decoding. Users can select from multiple digital filters, with Berkeley recommending the 1.16 or 1.24 interpolation filters as defaults. The Alpha DAC is praised for its ability to tame harsh recordings without losing detail, delivering a vivid, natural, and highly resolving sound with excellent transient response and dynamic contrast. It is noted for its smooth, refined presentation that reveals micro-detail and harmonic nuances without sounding analytical or cold. The unit weighs approximately 6.5 lbs and measures 1.75" H x 16.5" W x 10.4" D. Power consumption is about 25W. The Alpha DAC Series 1 remains a highly regarded DAC for audiophiles seeking a combination of musicality and accuracy in digital playback.
