Gustard Audalytic DR70 R2R DAC - Native 1-Bit DSD DSD512 PCM768kHz Fully Discrete Balanced Digital-Analog Converter (Black)

Discrete R2R conversion The DR70 uses a proprietary discrete R2R ladder DAC module that converts digital signals into analog through resistor-based switching. This architecture depends on very precise resistor matching, which is why it requires more care than modern delta sigma DAC designs.; Native 1-bit DSD playback For DSD, the DR70 uses a true 1-bit DSD D/A converter with native DSD512 support. In DIRECT DSD mode, the DSD signal is routed directly to the 1-bit switching array DAC circuit and bypasses PCM conversion. That means your DSD files stay in their native signal path instead of being translated into another format first.

; High-resolution digital input USB support PCM from 44.1 kHz to 768kHz at 16-bit to 32-bit, DoP from DSD64 to DSD256, and native DSD from DSD64 to DSD512. Coaxial and optical inputs support PCM from 44.1 kHz to 192kHz at 16-bit to 24-bit, along with DSD64 over DoP. Bluetooth 5.0 supports PCM up to 96kHz with LDAC, AAC, SBC, and aptX.; XMOS USB processing The DR70 uses a third-generation XMOS XU316 USB audio platform. It supports up to PCM 768kHz and DSD512, giving the DAC the bandwidth needed for large high-resolution files from a computer or compatible streamer source.

; FPGA signal management An FPGA handles logic functions, clock management, digital shaping, DoP demodulation, and PCM/DSD depop switching. In plain terms, the FPGA helps coordinate the digital side of the DAC before the signal reaches the conversion
