Applications & Specifications

Detailed technical specification:

Core DAC specs

  • Support up to DSD256 and PCM 384kHz
  • Dynamic range: better than 128dB, non-weighted (24bit, 20Hz-20Khz, -60dB)
  • Frequency range: 5Hz to 75kHz (-3dB point, @ 192kHz sample rate), 20Hz to 20kHz within 0.09dB
  • Total harmonic distortion better than -100dB (1kHz, non-weighted, 0dB-2V RMS, 24 bit)
  • Jitter: jitter from source is eliminated. SPDIF uses dual stage jitter eliminator

At reference quality level, the CY-5100dsd will take center stage.

Upgrade existing transport: connect using the SPDIF or TOSLINK input and instantly enjoy the obvious improved sound as jitter from the source is removed and the fully customized digital filter can set to match your personal music taste and existing equipment.

Replace old DAC:  Especially when your old DAC is more than 5 years old, the difference in sound quality will be dramatic.

To ‘up-end’ your existing media player: If you own a media player system, you can now enjoy improved quality sound. Simply connect your music system’s digital output to the DAC.

To use your computer as high quality music source:  The CY-5100dsd DAC’s supports up to 384kHz and DSD256 formats, so you have the option to do all digital filter processing inside the computer for superior sound or play the highest resolution files available today.

88.2 kHz, 176.4 kHz, 352.8 kHz (DXD) sample rates are also supported; use a player like the Foobar 2000 to play super resolution files in bit-perfect fidelity.
