The Cygnus is designed for the way audiophiles listen to music today—and the way they will listen to it in the future. It combines an advanced digital-to-analog converter with digital file access and browsing capabilities. Audiophiles can easily access music files stored on hard drives or USB sticks, and can use the Cygnus to achieve truly extraordinary sound from digital sources as diverse as satellite radio, cable and satellite TV set-top boxes, and of course the traditional CD player.



USB input for digital file playback: The Cygnus plays digital music files stored on any USB hard drive or thumb drive. FLAC, WAV and AIFF files are supported.

Legacy digital inputs: Five inputs are provided to connect digital source devices such as CD players and satellite radios.

Optional USB computer input: Interfaces the Cygnus directly with a computer for playback of files stored on the computer’s hard drive.

Custom digital filter: In order to deliver the best possible quality from the quad 32/192 DAC, we developed our own DSP-based digital filter. The listener can choose from several filter profiles, whichever best suits the music.

Fully balanced digital and analog circuitry: From the digital inputs to the XLR outputs, the audio signal is fully balanced. Using Constellation Audio’s Line Stage Gain Module allows us to achieve perfect balance of the positive and negative halves of the audio signal for maximum fidelity.

Separate power supply: In order to isolate the sensitive analog audio circuits from interference emanating from the digital circuits, the Cygnus uses a separate power supply enclosure. The power supply actually houses two separate supply circuits: a high-quality linear supply with an R-core transformer to feed the analog circuits, and another supply to power the digital and control circuits.

Browse digital music files from smartphones and tablets: Constellation Audio provides apps for Apple iOS and Android devices, so you can browse the digital files on a USB drive using your iPhone, iPod touch, iPad or Android. It’s as convenient and user-friendly as an iPod—but vastly better-sounding.

Full front-panel control: The 432 x 230-pixel front screen allows browsing of digital files from a USB drive, and also provides access to all of the user adjustments available on the Cygnus.

Machined aluminium chassis: The Cygnus’ precision circuits are housed in a solid machined aluminium enclosure with a minimum wall thickness of 8.2mm. Only an enclosure wall this thick can block interference from 50/60 Hz household circuits. The mass of the heavy chassis also helps damp external vibration that might affect the Cygnus’ precision audio circuitry.
