Description
Fully discrete R2R DAC with native DSD1024 decoding, FPGA clock management, and a CelWare-based network bridge. The R30 delivers an organic, natural sound through a precision resistor ladder, discrete Class-A analog stage, OCXO clocking, and relay-based passive preamp control — digital done differently.
