Cyrus DAC XP Signature

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+

CYRUS - What Hi-Fi 4 Stars
  • It uses a very familiar box, but Cyrus's DAC XP+ hosts massive ability
  • Excellent DAC performance
  • Stunning insight and precision

Cyrus DAC XP Signature Features:

  • True balanced DAC/ preamplifier painstakingly tuned to produce the trademark Cyrus sound
  • All digital inputs are upsampled to 32bit/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
  • Two entirely separate sections – A true dual mono D/A converter and a fully balanced analogue pre-amplifier. Keeping these processes completely separate means each can be given all of the power it needs on a separate circuit, avoiding any distortion or noise interference
  • Dual mono DAC cards - Dual mono DAC design improves the focus and the the clarity of the system
  • Fantastic detail and pure sound are ensured by the circuit’s expertly designed PSU - Based on a custom designed ultra low noise torroidal power transformer, the power 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. The factory setting is
    normal. Some listeners may prefer the inverted setting with their systems or for when playing particular recordings
  • Operation display mode: Small input, Large input or Large volume
  • Digitally-controlled analog volume control: ±0.2dB channel balance for accurate and stable soundstage

Product Overview

The DAC XP Signature features a true dual mono upsampling 32-bit DAC and a fully balanced preamplifier stage.

DAC XP Signature:
Dual mono, four 32bit/192kHz DACs balanced design - Low noise, 4 pole balanced analog filter - Expertly designed power supply, sophisticated regulation stages - Fully balanced analogue pre-amplifier

The upsampling DAC at the heart of the DAC XP Signature transforms any music you put into it into the highest possible 32-bit resolution. The fullness, depth and quality of the sound this produces is really impressive. The amplification process of the DAC XP Signature has also been painstakingly tuned to produce the trademark Cyrus sound: quality and purity guaranteed.
