Cyrus Pre DAC & X Power

Cyrus Pre DAC & X Power - STEREO (Germany) review
  • A particular strength of Cyrus has always been timing – and it still is. The components have exemplary qualities in terms of flow and rhythm - building up the sound pattern from the eminently important bass and middle range, which is very characteristically transmitted completely without breaks - is richly facetted and enormously natural.
  • Hardly any other piece of equipment in the same price range, but of a different make, will exceed or at best equal a Cyrus amplifier in reproducing the human voice.
  • The energy balance is also right and ensures that nothing is annoying or drifts off into the world of clinical analysis. The soundstage is nicely illuminated, well thoughtout in its depth and width. The space-time allocations are authentic, delivering an amazing image, and with it a convincing credibility of the dimensions illustrated. It sounds very open, free and detached.
    • Outstanding laboratory results. All values measured are absolutely at the top of the range, although it is of course the distortion, noise and crosstalk values which are the most interesting.
    • Elegant, rhythmic “swinger” and excellent pre-amplifier with high-quality D/A converter. Upgradable.
    • Respectable output performance, certainly sufficient for most applications with substantial spare capacity and top-quality values in all important categories such as extremely low distortion and low noise.
    • Despite its compact size, powerful and colourful mono/stereo power amplifier with pronounced audiophile virtues.

  • Cyrus Pre Qx DAC
    Overall rating: Outstanding 91 points 
    Price / Performance: Good - Very Good
    • +quick off
    • +very open and pointed in the space map
  • Cyrus X Power
    Overall rating: Good - Very good 74 points 
    Price / Performance: Good - Very Good
    • +black and edged in the bass
    • +punchy mids
  • Husqvarna Group from Sweden delivers the aluminum die-cast housing to Huntington, where it is fitted at the Cyrus headquarters.
  • It goes forward - deep black bass and potent. The energy was so strong that ultra-compact speakers seemed overwhelmed a trace in our test. The high speed and thrust yearn for an adequate customer - the power hungry, the stronger the picture.
  • Cyrus is on the opposite side of the ear flatterer. This had hands-on presence in an adagio of Monzart. Without the trace of sentimentality, crisp and information rich.
  • With Magico Q3 (40.000EUR): The extremely clean sound - In the listening room began the burn in period with the little Cyrus Vor-/End-Kombi. And indeed: The Q3 also runs on smaller amplifiers. Even at party levels made ​​the fun.

CYRUS - What Hi-Fi 5 Stars
  • Cyrus seems to be incapable of producing lack-lustre amplifiers - this preamp used in clonjunction with the 8 Power amp is a mighty combo
  • Exposes layer after layer of detail
  • Fast, punchy and precise delivery
  • Sensational timing

Cyrus Pre XP d & 8 Power

Hi-Fi Choice logo
  • Detailed and subtle, with little character added to sound
  • "They are capable of a very high degree of subtlety"
  • "One of the most revealing combinations in the test, its character (or lack of it) making it a very honest and straightforward part of the reproduction chain"
