Features

  • Auto-mute circuitry for “no-pop” power cycling
  • Digitally controlled trims for line up procedures
  • Dynamic range of 127dB (typ.)
  • Low Phase Noise Oscillator circuitry
  • Up to 192 kHz sample rate (DSD for the DA8P)

The DA8 (up to 192kHz) and the DA8P (up to DSD) have consistently shown in testing to be the quietest multichannel D/A conversion modules available anywhere.

Design

The original design of the 8-channel DA convertor board has been a great tool in setting a standard for critical listening and monitoring for all users. Now incorporating the ES9028PRO chip, users can benefit from even more impressive specs with a typical Dynamic Range of 125 dB (> 127 dB A-weighted) and THD+N in excess of – 116 dB (this latest number being actually close to the measurement limit of our Audio Precision equipment maxing at 118 dB THD+N).

In addition, Low Phase Noise Oscillator circuitry has been added to further improve the absolute transparency and stereo image of an analogue signal, effectively void of both jitter and wander.
