Azur 840W Class XD™ power amplifier

Cambridge Audio has taken the Azur 840 series to its peak with the introduction of two new models – the 840E pre-amplifier and 840W power amplifier. The 840W is a high-end power amplifier that has been designed by the same team behind the 840A and uses an evolution of Cambridge Audio’s hugely innovative Class XD™ technology for a highly detailed naturally musical performance. The second generation Class XD is now complemented by a new output stage carefully adjusted to integrate with this novel technology, revised balanced inputs for lower distortion and noise. An awesome 200W @ 8 Ohms gives excellent load driving ability or, a truly massive 500W bridged mono can be harnessed for even ‘difficult’ high-end speakers.

At the core of the 840W’s strength is a patent pending, Class XD (crossover displacement) technology (first seen in the 840A) and which has been subtly revised following continuing post-launch development and critical evaluation. This unique design gives pure Class A operation at low levels, moving smoothly into an enhanced version of Class B at higher levels. This system should not be confused with Class AB, which inherently generates greater distortion at high levels than a pure Class B design. XD technology feeds a controlled current into the output stage actively displacing the crossover point in a new way so that the usual Class B crossover point no longer occurs at zero volume - the worst possible position in terms of distortion – but at a significant output level. The result is a smooth and linear transition between the two modes of operation, which differs significantly from the abrupt, gain transition of a Class AB amplifier. To facilitate this, the Azur 840W amplifier includes a massive, oversized low flux toroidal transformer, incorporating a silicone-steel screen.

In our ongoing development of Class XD we have conducted exhaustive research into further improvements of our amplifier designs to squeeze everything out of this innovative technique. This in turn led to a new output stage topology being developed which has been incorporated into the 840W. Four pairs of very high current output transistors are used per channel (for the amplifier output) plus two extra high current transistors per channel for the XD circuit.

The 840W can also be used in either bi-amped or bridged mono configurations. When bi-amping, one 840W (of the pair) powers each speaker so that the tweeters and woofers each have their own dedicated amplifier channel. Alternatively the bridged mono mode allows the use of two 840Ws with each configured as a 500 watt monobloc. In fact combinations of the two regimes allow the use of one, two, four or even more 840Ws to be used, taking it to the truly stratospheric high-end.

Also included is the latest development of Cambridge Audio’s proprietary CAP5 protection system. CAP5 (Cambridge Audio Protection 5) is an innovative and intelligent protection system. It constantly monitors the amplifier, without degrading signal purity, ensuring ultimate reliability. There is also short-circuit detection and a solid-state temperature sensor with over-heat cut out to ensure the amplifier delivers high performance.

All this proprietary engineering is housed within our low resonance, acoustically dampened chassis which includes a 7mm thick aluminium front panel.

"... the Cambridge combo remains faithful to the recording, yet is neutral enough to be a solid recommendation for just about all loudspeaker/source combinations. Welcome to the big league, Cambridge Audio; you’ve certainly turned up with your best game."

Tone (New Zealand) January/February 2009




"Simply put the 840W challenges any high-end hedging about Cambridge Audio. The 840E and 840W represent two of the most satisfying debuts in recent years."

The Absolute Sound (USA) January 2009

(Solid-state amp of the Year)




"Van harte aanbevolen."

"Whole-heartedly recommended."

HVT (Netherlands) January 2009

(Reviewed with Azur 840E pre amplifier)





"The Cambridge Audio Azur 840E/W pre-amp and power amp get just about everything right. They're built to very high standards, feature innovative technology, are simple to operate, and are equipped with plenty of features. Most of all, they sound musical. And that's the most important talent of all."

Audio Video (South Africa) November 2008





"Y así es, con el todo superando la suma de la partes y unas posibilidades operativas absolutamente fuera de lo común en realizaciones de su precio. En consecuencia, se impone una recomendación entusiasta... “qué menos!”"

"... the 840 Series' performance far outweighs the sum of its parts... the multitude of possible set-up options are unheard of at this price and for that reason they are whole heartedly recommended."

Alta Fidelidad (Spain) November 2008

"Truly accomplished pre-power combination with massive authority and breathtaking dynamics at the price."

Hi-Fi World October 2008


"두말 할 필요가 없는 좋은 결과....특별히 흠잡을 부분이 없을 만큼 인상적인 소리를 냈다."

"Needless to say, it is a great result... It delivers an impressive sound which is above criticism."

Audio (Korea) September 2008

(Reviewed with Azur 840C upsampling CD player and 840E pre amplifier)


"The 840E/W combo offers great imaging and smoothness, and enough watts to give a good feeling of dynamic headroom with averagely sensative speakers. Cambridge has come up with a one-two punch that will be hard to beat. It would be impossible not to recommend this impressive combination."

Hi-Fi News August 2008


"The new 840E/W represent a new era for Cambridge Audio in terms of price and performance. Audiophiles who aspire to the high end but only have modest spending power will welcome the performance per pound the duo offers, too."

"제한된 금액 내에서 Cambridge Audio는 이 두 덩이의 앰프에 최고의 기술을 담아 넣었다... 그런 앰프들에서 느껴볼 수 없었던 강력함이 무엇인지를 느끼게 해줄 것이다."

"Cambridge Audio has put its best technologies to date into these two units at a very low price..."

What Hi-Fi? Sound & Vision (Korea) June 2008




"캠브리지 시스템이 내어주는 소리의 가장 큰 덕목은 그 공간감이라 할 수 있겠는데... 라이브로 녹음된 음원의 현장감을 묘사하는 데 있어서 아주 일품이었다고 판단되었다... DVD를 감상해보았다...현장감을 표현하는 다양한 음향효과를 설득력있게 제시할 뿐만 아니라...연기의 열정 같은 것을 청각적으로 표현하는 게 인상적이었다."

"The biggest benefit from the Cambridge Audio system (840E&W) is the sense of space... It was able to express the realism of live sound... with DVD it presented the realism and surround effects persuasively... I was impressed that I could feel the passion of the actor's performance just by listening"

Audio (Korea) May 2008

(Reviewed with the Azur 840E pre amplifier)



"Le prix Innovation obtenu au CES 2008 nous semble pleinement mérité. A découvrir sans hésitation."

"It wholly merits its CES Innovations award and is recommended without hesitation."

Son et Image (Canada) May 2008






"The 840W is a novel high-end power amplifier with engineering passion at its heart. Despite being surprisingly inexpensive, it is sophisticated, upgradeable and enormously powerful yet still musical and light of touch."
