  • Ultra-high-speed FPGA harnesses digital processing power to implement innovative MDSD reproduction with double-speed high-precision moving-average filter circuit.
  • Sixteen MDS type D/A converters driven in parallel. Each channel uses two Hyperstream™ DAC chips (ES9018) in parallel.
  • “Direct Balanced Filter” performs totally separate analog low-pass filtering for line and balanced signal paths.
  • D/A converter printed circuit boards made from glass fluorocarbon resin with low dielectric constant and low loss.
  • EXTERNAL DSP input/output connectors (HS-LINK and optical) allow insertion of DG-58 in signal path.
  • Seven digital inputs: HS-LINK, balanced, coaxial (2), optical (2), USB.
  • Coaxial and optical digital outputs.
  • Line and balanced analog outputs. Phase selector switch for balanced output.
  • Completely separate construction of digital and analog sections, each powered by a dedicated high-efficiency toroidal transformer.
