In addition to coaxial SPDIF output, the DD-900 SACD Transport will be to output DSD stream via its proprietary HS-Link connection to the DC-901 DAC.
The DAC sports HS-Link, coaxial, Toslink and AES/EBU inputs as well as a high speed 24/192kHz capable USB input. It also has a "digital tape loop" I/O after the de-jitter circuit and just before the DAC chip itself for connection to a digital signal processor. The DC-901 uses two ESS SABRE32 DAC chips, one per channel. Volume controlled in the digital domain. Balanced and unbalanced outputs.
Pricing approximately US$10,000 for each unit.
