The most important conclusion: Cyrus series 40 plays modernly, precisely and dynamically, while maintaining the typical musicality and coherence of the brand. This is a set that focuses on control, speed and clarity, but does not fall into dryness.

  • Dynamics - very good, fast signal rise, excellent micro-dynamics.
  • Bass - tight, fast, well-controlled; more contoured than massive.
  • Midrange - clear, neutral, without warmth; high vocal clarity.
  • Treble - detailed, open, but not aggressive; great precision of location.
  • Soundstage - organised, with a clear outline of sources, wide and stable.
  • Overall character - technical, but not cold; focused on accuracy and control.

This sound will appeal to those who value analytical quality, speed and clarity, and less to those looking for tube warmth or softness.


Construction and functionality

The series 40 consists of four devices that can be combined in various configurations:

  • 40 AMP - integrated amplifier, the central element of the system.
  • 40 CD - purist CD player with a slot mechanism and excellent digital section.
  • 40 ST - streamer with extensive networking capabilities.
  • 40 PSU - external power supply that improves the parameters of any of the three devices.

Key construction features:

  • characteristic, compact Cyrus enclosures, refreshed as part of the anniversary series,
  • high quality of workmanship and minimalist design,
  • the possibility of gradually expanding the system (e.g. adding a PSU as an upgrade),
  • very good digital sections in CD and ST,
  • stable operation and high technical quality of the entire set.


Test impressions and overall assessment

The Audio Test highlights that the 40 series is a mature, consistent, and very coherent system that works best as a complete unit. The 40 AMP amplifier is the foundation, and the sources (CD and ST) offer a high level of signal quality. The external power supply 40 PSU brings a noticeable improvement in terms of:

  • background clarity,
  • stage stability,
  • dynamics,
  • bass precision.

The system is rated as audiophile, fast, and precise, with a clear emphasis on control and neutrality. It is a proposition for those who want to enter the high-end world in a compact form and value the possibility of gradual expansion.


Who is the Cyrus 40 series for?

For those who:

  • prefer a neutral, fast, and analytical sound,
  • want a system with compact dimensions but high quality,
  • value the possibility of modular expansion (PSU as an upgrade),
  • listen to a variety of music, including recordings that require precision and control,
  • are looking for a set that works best as a complete, coherent whole.

Less suitable for those who prefer a warm, soft, or very 'valve-like' sound.
