Cambridge Audio Azur 851E Preamplifier
Want Purity and Clarity? You Got It: Azur 851E Touts Barely Measurable Distortion and Noise
Azur 851E Built to Demanding Audiophile Standards: Terrapin Modules Separate Amplifier and Signal Impedance for Optimum Sound, Flexible and Controllable Trigger Outputs Broaden Integration Capability
Purity. Clarity. Few, if any, traits, are more prized in preamplifiers. Cambridge Audio's Azur 851E has both in spades. This exceptional analog preamplifier delivers so little harmonic distortion and adds so little noise to incoming signals that it can barely be measured. As audiophiles know, that's a very good thing. Add an innovative solid-state volume control that offers precise control, accurately retains channel balance at low levels, and offers truly linear performance, and you have a preamplifier destined for high-end systems.
Azur 851E is designed as a true audiophile component throughout. Terrapin impedance buffering modules separate amplifier and signal impedance, delivering consistent sound across different sources and offering amazing stereo separation and imaging. It also comes with flexible and controllable trigger outputs and control bus for integration with power amplifiers as well as an all-metal chassis to isolate the electronics from unwanted external interference. Eight inputs, including three XLR balanced inputs for superior audio fidelity, make 851E connectable to a broad range of sources.
From a technical standpoint, Azur 851E touts seriously incredible distortion ratios. Total harmonic distortion is < 0.00045% @1KHz or < 0.000057% @20kHz. Signal-to-noise (unweighted) is < 110dBr, < 90dBU. These figures are at the very limit of what can be even measured. And while the volume is controlled digitally, the volume control is analog. Toss in a remote control, and Azur 851E leaps to the top of its class.
