Cambridge Audio Azur 840E preamplifier & 840W bridged monoblock amplifiers - various


Connections:12v trigger in/out, control bus in/out, IR emitter in.

Would you believe that the amp is just as feature-laden? When it has indicators on the front for STANDBY/ON, OUTPUT, PROTECTION, CLIPPING, BRIDGED, and MONO it's going to have some extra doodads on the back. Those doodads are comprised of easily...

Cambridge Audio Azur 840C CD player - 1499.00


The CD player is on the way to becoming a relic.

Cambridge Audio Azur 840C Review Update: The week of November 17th, 2008 saw one of my purchased 840C players returned to Cambridge Audio for warranty repair. It seems the player was not locking on to a digital signal sent from the Ayon CD-3...

Cambridge Audio Azur 840C CD Player


Such an impressive feature and technology list, however, tells you nothing about how the player sounds. To know that, you must listen. Dropping the 840C into my reference system, I was stunned by its overall sound quality. I knew immediately that the...

The Cambridge 840C CD player delivers the best CD playback I've heard from any player under $5k-and it costs $1499. Not only is the 840C easily the greatest value in digital sources in my experience, it must be considered one of the greatest bargains...

Cambridge Audio Azur 840C


It's not easy to do something really new with CD replay, especially at a sensible price, but Cambridge seems to have achieved it with the 840C. The big feature here is 384kHz upsampling...

384KHz upsampling, Well-balanced sound

No one area of particular excellence

An undemonstrative player that nevertheless admirably combines tonal neutrality, effortless detail and a fine sense of rhythm and timing

Cambridge Audio Azur 840C


In action the 840C is a revealing, even sizzling player. It has a strong sense of definition and plenty of welly when it's called for. Not as refined as the Cyrus, it nonetheless gives that player a run for its money with a tight and nimble bass and a...

A ton of features for the money and a well rounded, precise and solid sound to boot

For the money, none

Cambridge Audio Azur 840C


This Cambridge Audio CD player (Azur 840C) is pricey, but you get what you pay for.

Fine tonality, fabulous bass quality, great detail

A very slight smudging of images

There isn't a CD player at the price that offers anywhere near as much.

Cambridge Audio Azur 840c


The other Steve below who posted 3 stars in his April 29, 2012 review probably works for a store selling competitor's gear, but no Cambridge. Well, I also happen to own the Teac PD-H600 (for my office system) and frankly, as good as the TEAC is, it is...

Cambridge Audio Azur 840c


Great player in balanced connection with Cambridge Audio 840A but both machines have proven highly unreliable and needed repairs. It's a real hassle having equipment and not knowing whether or not it will work properly. Frankly, I would never buy their...

Cambridge Audio Azur 840c


Took my 840C in for repairs today, second time since new. This is a good sounding unit when working, I use the digital input for a Squeezbox, server system and sounds very good.4 stars for sound and flexability, 3 stars for quality issues.

Product Specifications

The 840C marks the zenith of Cambridge Audio's critically acclaimed Azur line up. Like all Azur products, the 840C promises unseen levels of performance and engineering excellence to the price points in question. But rather than redefining expectations in the entry-level market, the arena most often associated with Cambridge Audio, the company will reinvigorate the mid-end price sector. The 840C embraces a raft of proprietary technologies including ATF (Adaptive Time Filtering) asynchronous up-sampling technology which has been developed in conjunction with Anagram technologies of Switzerland. This system intelligently interpolates 16-bit/44.1 kHz CD data to 24-bit/384 kHz data, through the use of a 32-bit Analog Devices Black Fin DSP (Digital Signal Processor). This in turn feeds two 24-bit/384 kHz DACs from the same company in dual differential formation. Each DAC handles just one channel for excellent stereo imaging, operating fully in differential mode for exceptionally low distortion and noise. Both unbalanced RCA and balanced XLR outputs are fitted. Two digital inputs are also provided which even allow the up-sampling and playback of other sources such as a DVD player via the Azur 840C. In addition, a recording digital output can even allow bit-for-bit data or upsampled data at 48, 96 or 192 kHz to be recorded by a suitable device. A control bus in/out, an IR emitter in connection and an RS232 port are provided for easy multi-room connectivity. The RS232 protocol enables a two-way interface with third party home automation touchscreens. As with all Azur products, the foundation of the 840C's excellence is a bespoke chassis. This comprises an incredibly thick 7mm front panel and extruded side panels, both fashioned from aluminum, which combines with a 2mm formed steel base plate and specially designed vibration absorbing feet. The result is an ultra rigid, low resonance, acoustically dampened platform for the electronics to sit in.
