Because it is functioning as separate DAC, our custom ASIO drivers must be installed in your computer for use with the USB 2.0HS input.
Sonically, the REF CD9 is in a new class, combining the magical musicality of tubes with new levels of transparency and aliveness. The REF 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.
Production is already underway, with units available this month. Please contact your sales representative to hear this Reference product yourself; it is much more than an evolutionary advancement.
Sincerely,
Audio Research Corporation
