About Cambridge Audio:
Cambridge Audio has been at the forefront of
British hi-fi for more than thirty five years. Since its inception in 1968,
Cambridge Audio has brought some of the most innovative and technologically
advanced products to market.
During the ‘70s, the P40, P50 and P110 amplifiers established the
international reputation of the Cambridge Audio brand. The ‘80s saw Cambridge
Audio launch the world’s first two-box CD player. In the ‘90s, the DacMagic
was the first product in the company’s history to win an esteemed What Hi-Fi?
Sound and Vision Best Buy award. The new Millennium saw Cambridge Audio
continue to innovate with its award winning DAB digital tuners and of course the
highly-acclaimed Azur range.
Cambridge Audio has a philosophy of using only the finest quality components,
all models are developed using state-of-the-art test and measurement equipment
and feature the latest technology. This commitment to engineering excellence,
combined with state of the art manufacturing facilities, means every Cambridge
Audio product offers the best possible performance. Prior to launch, all designs
undergo rigorous evaluation involving meticulous listening and fine tuning.
But the main reason for Cambridge Audio's success... our people. We employ
nearly 80 colleagues, the majority at our London headquarters, including over 20
engineers in a dedicated research and development facility. Every member of our
team shares the same passion for hi-fi and home cinema as you – our customers.
That’s why we always go the extra mile to make sure we only produce products
we're proud enough to take home – and trust us we do!
Cambridge Audio products are distributed in over 45 countries and the company
turns over in excess of $40 million.
About Cambridge Audio Azur Range:
Cambridge Audio’s Azur range of hi-fi
electronics was introduced in 2003. It was the company’s first completely new
series of products for nearly five years. While Cambridge Audio had an enviable
reputation for engineering quality components at great prices, it was felt a new
series was needed to tackle the demands of the new millennium.
Our engineers were given a clean slate from which to work. They went back to the
drawing board intent on building the ultimate series of electronics. Azur has
been designed from the ground up and takes in many innovative, proprietary
technologies. All the years of painstaking audiophile research and development
has paid off. Azur is by far and away the most critically acclaimed range of
hi-fi and home cinema components Cambridge Audio has ever introduced.
The Azur name is also your guarantee of the class leading performance. Don’t
take our word for it, the rapturous applause Azur has received from the
world’s hi-fi press is testament to the performance, build quality and value
for money featured in the latest Cambridge Audio range.
Importance of a Good Amp:
The amplifier is the workhorse of your system. It is responsible for delivering electrical power to your speakers. You will need a quality amplifier to get the best from your speakers and make the most of your source signal.
In very simple technical terms an amplifier takes the signal and – as the names suggests – amplifies it. It takes this weak audio signal and boosts it so that it is powerful enough to drive a speaker. This power is measured in Watts. This figure is in itself of very little importance to sound quality. Just ensure your amplifier has enough Watts to drive your speakers i.e. it matches their lowest power rating.
Key features of an amplifier can include a second set of speaker outputs, remote control, a headphone output, and tone controls, which you should be able to bypass. Cambridge Audio Azur amplifiers all come with these features.
Just as important as the amplifier are the cables that run from it. There’s no point having a great power source and using poky cables. Budget to spend about 10-15% of your entire system cost on cables.
Cambridge Audio Azur 640A Version 2 Integrated
Amplifier Product Summary:
The Azur 640A is back as a Version 2 with a raft of upgrades. It
now thumps out a whopping 75 watts thanks to a higher specification toroidal
transformer. Moreover, a chunkier heat sink allows the amplifier to dissipate
more energy and run cooler than before, meaning the amplifier can operate
harder, for longer.
The Azur 640A V2's sensitive preamp circuitry has also been significantly
redesigned, generating lower noise and THD (total harmonic distortion), while
delivering greater levels of transparency. At the heart of these enhancements is
a completely new input PCB with buffering on every input which has radically
reduced crosstalk and provides even better imaging characteristics.
The Cambridge Audio Azur 640A V2 also sees improvements to the power amplifier circuitry layout,
with many small but significant refinements further reducing distortion and
improving the drive capability with real world speakers.
The Cambridge Audio 640A V2 is now Incognito Ready!
To allow seamless integration with multi-room entertainment systems, the Azur
640A V2 now has Control Bus input and output as well as an IR emitter input.
Outputs for Cambridge Audio's new Incognito multi-room system are even included.
This enables self-amplified Incognito multi-room keypads to be connected to the
640A V2 allowing the hi-fi system to be shared with up to two other rooms. Each
gains local control.
All this technology is housed on Cambridge Audio’s hugely respected low
resonance, acoustically damped chassis, which takes in a thick aluminium front
panel. Here you’ll find changes to the volume, tone and balance controls, with
new pots offering better feel, as well as greater accuracy and improved channel
matching at low volumes.
There’s also a heavier steel skin on the main volume knob adding greater and a
better feel. Completing the upgrades is a highly ergonomic navigator style Azur
remote handset.
The new Cambridge Audio 640A Version 2 is available in silver or black.
