This model works as a digital transport in the absence of a built-in digital-to-analog converter. Removing additional circuitry allows CDt to focus solely on data extraction and delivering high-performance digital output.
The success of CDi lies in the design of the two main functional components of any CD player: the drive and the DAC. The proprietary Servo Evolution drive reduces the load on the servo tuning of the read head and removes the associated noise and interference in the audio path, and the 32-bit DAC came almost unchanged from a separate Cyrus DAC XP SIgnature DAC.
The absence of a DAC unit and an analog part in this model create a more favorable environment for the formation of a digital output stream, which has a beneficial effect on sound quality.
The Cyrus CDi-XR full CD player uses a proprietary second-generation QXR DAC. The Cyrus Audio developers emphasize that this is a more advanced solution compared to Burr Brown chips from Texas Instruments, which were used to build previous generations of the company's CD players. The DAC unit is located in a fully shielded section of the player's body and is optimized for decoding material from CDs with a resolution of 16 bit / 44 kHz.
