Features

  • High quality toroidal power transformer
  • High-performance DAC-ESS ES9026PRO.
  • USB DAC: PCM 32 Bit/384kHz and DSD DSD64 (DoP)/DSD128 (DoP) DSD64/DSD128/DSD256 (ASIO Native).
  • COAXIAL/OPTICAL DAC: PCM 24 Bit/192kHz and DSD DSD64 (DoP).
  • Placed balanced/unbalanced headphone output: max output power 2000mW + 2000mW @ 32ohms.
  • Placed RCA/XLR input/output interface: could be a Preamplifier.
  • Volume control system: 128 step attenuator. Accurate control volume to achieve left/right channel balanced.
  • Isolation circuit: completely separates the grounding of the digital and analog sections.
  • Volume/Source/Sampling display using OLED has excellent visibility.
  • The 4mm thickness of the aluminum chassis to effective to blocks EMI/RFI interference.
  • The full-metal body realizes both vibration control and elegant style in an A4-size body that enables placement on a desktop to be a PC HIFI system or to be a small stereo system.
