The Reference CD9 incorporates four digital inputs: Asynchronous USB 2.0HS, AES/EBU, RCA, and Toslink. All inputs handle 24 bit / 192k resolution. As you would expect, the Reference CD9 retains the Philips PRO2R transport, still the best dedicated CD mechanism available. It is simply unsurpassed for compact disc playback. Benefitting from what we have learned in the development of the Reference DAC and the DSPre, the REF CD9 utilizes quad 24-bit DACs running in mono mode, with dual master oscillators; one for 44.1/88.2/176.4 sample rates, the other for 48/96/192kHz sample rates. Sample rate conversion is selectable for all inputs, allowing playback in native resolution or via upsampling, including compact disc and—for the first time—the USB input. Additionally, there is a selectable digital filter, with either fast or slow rolloff.

On the bench, the bandwidth of the Reference CD9 is five times that of the CD8, with one tenth of the distortion, greater dynamic range, and it is also quieter. Like the Reference 5SE, Reference PH2SE and Reference DAC, the analog section is vacuum-tube, with four 6H30 dual-triodes, and there is vacuum-tube power-supply regulation featuring a 6550WE with a 6H30. The magic is continued. The front panel has the familiar, dimmable CD display on the left side. On the right side there are three vertical rows of LEDs to indicate sampling rate, input selection, filter and power. In addition to the digital inputs, the back panel includes Digital Outputs (AES/EBU and BNC), single-ended RCA and balanced XLR outputs, and a 15A IEC power connector. Due to its function as a separate DAC, our custom ASIO drivers must be installed in your computer for use with the USB 2.0HS input.

Sonically, the Reference CD9 is in a new class, combining the magical musicality of tubes with new levels of transparency and aliveness. The Reference CD9 sounds “faster” with greater transient speed, improved dynamics from top to bottom, much greater resolution of inner detail, with a focus and purity that is captivating. Rhythm, pace and timing are better than ever, something you must hear to appreciate. It’s time to hear your music in High Definition®.
