"By any high-end standard, the Azur 840E and its 200Wpc partner, the 840W, are elegantly and conservatively styled—appropriate to the segment they aim to compete in. The acoustically damped casework is absolutely first-rate with a heavy 7mm front panel of extruded aluminum and aluminum side-panels. Every finished edge is satin smooth, with tight seams corner to corner. In the case of the 840W, the designers implemented some creative crosshatched venting to aid the amplifier’s thermal efficiency. Substantial heat sinking lurks beneath. The front panel of the 840E preamp is dominated by an LCD display (adjustable for intensity), which is flanked on each side by a vertical row of input buttons. The large volume-control knob is in actuality an attenuator-type. It’s a premium resistor-ladder design with 1dB increments and is relay-based with gold-plated contacts—far more precise and stable over the long run than the typical wiper-style volume pot. This mechanism isn’t quiet. It ratchets up and down with the clatter of a socket wrench but at the end of the day its precision is reassuring. Via the “Mode” button there are treble and bass and balance controls, but this circuitry can be bypassed with a push of the “Direct” button. In another nod to pushing the high end forward, Cambridge Audio decided to forgo the ubiquitous op-amps normally used for driving low-level gain stages and designed and manufactured its own proprietary TerraPin (signifying ten-pin) discrete modules."
