• 👍 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 44.1kHz 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 44.1kHz 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 stage, keeping timing and format handling under tight control.
• 👍 Clocking and power design ▶️ The CK01 clock module provides femtosecond-grade timing for the system. The DR70 also uses independent voltage regulation for each circuit group, along with a built-in low-noise power supply and support for external 9V–18V DC input. This helps reduce interference between sections of the circuit, which matters when small timing and noise differences can affect a digital audio chain.
• 👍 Balanced and single-ended output ▶️ The DR70 includes simultaneous RCA and XLR outputs, making it easy to connect to powered speakers, a headphone amplifier, an integrated amplifier, or a fully-balanced downstream system. Output is fixed at 2Vrms over RCA and 4Vrms over XLR, with 100Ω output impedance for both connection types.
