The compact disc is a format now more than 30 years old, with a catalog of hundreds of thousands of titles; simultaneously, digital downloading and computer music storage is skyrocketing in popularity. Combining a super high-resolution compact disc player and digital-to-analog converter in one compact chassis, the CD6 is a perfect fit for modern music playback. The CD6 is positioned to optimize most any digital format with spectacular results. The Audio Research CD6 offers disc playback via the Philips Pro2 transport (still considered the industry standard), plus four digital inputs (asynchronous USB, coaxial RCA and two toslink). All inputs handle 24 bit / 192k resolution. Benefitting from what Audio Research has learned in the development of the REF DAC and CD9, the CD6 utilizes quad 24-bit DACs running in mono mode, with dual master oscillators for highest performance; 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 USB. Additionally, there is a selectable digital filter offering fast or slow rolloff. In addition to the digital inputs, the back panel includes two digital outputs (AES/EBU and BNC), and single-ended RCA and balanced XLR outputs. Sonically, the CD6 is a stunner, uncovering new musical detail in every corner of your recordings and providing startling dynamics, both micro and macro. The top end is extended, airy and pure, while bass definition and impact are precise and powerful. The recording venues are lifelike, broad and expansive or close-up and intimate, depending on what was captured by the engineer. Like great analog, listening to music through the CD6 draws you into the performance, not just the notes, with resolution and transparency that are in service of the music. Experience your music in High DefinitionÂ®.
