Cyrus DAC XP Signature - What Hi-Fi 4 Stars
  • Play Tchaikovsky’s 1812 Overture and the XP continues to impress. It tracks the tiniest details with ease, delivering every inflection with pristine definition.
  • When the music really explodes the Cyrus takes it all in its stride delivering wide-ranging dynamics with plenty of composure. Once again we’re struck by the level of control here.
  • We’re pretty happy with the soundstaging. It’s impressively focused and nicely layered. 
  • If you’re already a fan of the Cyrus sound, jump right in. Even if you’re not it’s well worth a listen.
  • A fast, precise and detailed sound
  • Impressive clarity
  • Good upgrade potential

Cyrus DAC XP & X Power

CYRUS - What Hi-Fi 5 Stars
  • Cyrus has taken an odd approach that works fabulously.
  • A terrific sound that brims with speed, dynamics and agility

Cyrus DAC X+ Features:

  • True balanced DAC tuned to produce the purest Cyrus sound
  • All digital inputs are upsampled to 24bit/192kHz. - The D/A converter will upgrade any digital source
  • Sophisticated re-clocking circuit - High accuracy sources are digitally re-clocked by a close tolerance circuit with triple quartz references ensuring low jitter
  • True balanced topology throughout - Fully balanced topology from the digital domain to the analogue output stage
  • Dual mono DAC cards - Dual mono design improves the focus and the the clarity of the system
  • Expertly designed PSU - The power supply is cascaded through a number of sophisticated regulation stages and isolation techniques that ensure each section receives an unrestricted, noise free, power supply
  • Extensive PSU refinements - Greater resolution from the analogue stages, the subtlety and emotion of the musical performance is preserved
  • Extensive use of Star-earthing - Ability to resolve to very low signal levels
  • Optically isolated digital control system - Control signals have no influence on the music signal
  • PSX-R₂ socket to upgrade for greater resolution and dynamics
Cyrus DAC XP Signature - Digital Filter Response: Fast or Slow roll-off Cyrus DAC XP Signature - Phase adjust: Normal or Inverted
  • Digital Filter Response: Fast or Slow roll-off - Gives two settings for the digital filtering of the DAC stage. Choose your preference of Fast or Slow roll-off by auditioning some of your favourite tracks
  • Phase adjust: Normal or Inverted - Sets the audio phase for the DAC. Some listeners may prefer the inverted setting with their systems or for when playing particular recordings
  • Operation display mode: Small input or Large input

Product Overview

The DAC X+ upsampling audio D/A converter features dual mono DACs and a balanced audio design throughout the analogue domain. The DAC X+ is a high-end upgrade for a CD transport or other digital audio sources, connecting between the digital outputs of the sources and a preamplifier.

Inside, four fully balanced 24-bit DAC chips convert digital sources to analogue in a process which has been painstakingly designed and tested to ensure high definition sound quality, no interference and no distortion.
