Audio Research introduced its first
Reference series CD player in 2005 with the Reference CD7, then evolving into
the Reference CD8 in 2008. Both players met with critical acclaim for their
musicality and reproductive accuracy. People still want to play their CDs, but
they also want to add other digital sources such as computer audio to their
music systems, so we created the Reference CD9 CD Player/DAC. It combines the
best of both, a super high-resolution compact disc player with a super
high-resolution digital-to-analog converter that is stunning in its musicality.
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.
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
