Very few hours; like new. This is the currently available flagship DAC from Berkeley. Buyer to pay shipping/insurance as well as any Paypal fees.
Retail $20,000 Audiogon Blue Book $12,178.13. You may see the Berkeley dad selling for / sold for less but that doesn’t account for newest model series 2 with the MQA capability. That adds thousands to price.
The Berkeley Audio Design Alpha DAC Reference Series 2 MQA’s unmatched time domain resolution, low noise digital processing and highly accurate analog circuitry combine to reveal the amazing potential of MQA encoded audio. The Alpha DAC Reference Series 2 MQA replaces the Alpha DAC Reference Series 2 which will no longer be produced. In addition to providing MQA Rendering at an unmatched level of audio quality, the Alpha DAC Reference Series 2 MQA features significantly improved audio quality with standard PCM, non-MQA recordings.
