Azur 851D Offers Instant Bluetooth Compatibility: All Audio Upsampled to 24-bit/384k
Dual Analog Devices AD1955 DACs, Asynchronous USB Input, Built-In Headphone Amplifier, and Excellent Toroidal Transformer: Azur 851D an Audiophile Workhorse
Cambridge Audio's reference DAC is built like a fortress, outperforms higher-priced competing DACs, includes an outstanding asynchronous USB input and built-in headphone amplifier, and makes digital sound refined. Azur 851D also handles digital audio from just about any source you could care to connect to it. Sonically, it works to uncover every last detail hidden in your music. Its high-performance start with second-generation ATF upsampling that upsamples all audio to 24-bit/384kHz. From MP3 to high-res downloads, you'll hear new colors and textures as well as greater dynamics and phenomenal tonal balance.
Remarkably flexible, Azur 851D comes loaded with digital inputs, including coaxial, Toslink optical, BNC coaxial, and AES/EBU. A great-sounding asynchronous USB input is standard. Add Bluetooth wireless connectivity via the APTX-compatible BT100, included free with 851D. Inputs come in at up to 24-bit/192kHz quality and are then upsampled before being output. You'll be astonished at the difference in quality Azur 851D makes to every source (set-top boxes to media streamers, smartphone docks to computers) you pass through it.
In addition to ATF2 upsampling, Azur 851D owes its overachieving performance to dual Analog Devices AD1955 DACs, an audiophile-grade digital preamplifier (DSP), and several other premium components, not the least of which is a toroidal transformer that delivers smooth power delivery under pressure. Every component is hand-picked for supreme quality and unstinting sonics. As such, Azur 851D suits nearly every type of listener need and setup. It outputs to either unbalanced RCA or balanced XLR, as found in many high-end separates, or to headphones via its built-in, low-distortion headphone amp. You even get three filter options to customize the sound to your taste.
Cambridge Audio also made certain Azur 851D possesses architecture that serves the sound. Its casework combines massive structural rigidity, damping elements, and acoustic-resonance control. The proverbial cherry on top, Azur 851D can even be configured as a digital preamplifier via its variable output that can be connected to a power amplifier or active speakers.
