Azur 851E and 851W
Pre and Power amplifiers
The ultimate amplifier combination
The inside story
Helping us to achieve this incredible sound are some other key
features rarely seen at this price point.
• Immense power. Into 8 Ohms, the 851W outputs 200W per channel in
stereo mode. Into 4 Ohms, this figure increases to 350W per channel!
• Flexible conguration. The 851W can be used in stereo, bi-amped
or bridged mono configurations. In bridged mono mode into 8 Ohms
the 851W is a 500W monoblock amplifier. Into 4 Ohms, this figure
increases to an incredible 800W!
• Class XD amplication. The 851W runs our proprietary Class
XD amplification. This combines the best of Class A and Class AB
amplification, delivering the sound quality of a Class A amp while
retaining the efficiency of a Class AB amp.
• Incredibly low distortion. Within the 851E, every component is
designed not to interfere with the audio signal input and output, meaning
that harmonic distortion and noise are so low that they’re almost
impossible to measure.
• Further improvements. The 851E also improves over its predecessor,
the highly rated 840E, with a more versatile and high-end-friendly range
of inputs and an innovative solid state volume control – this retains
audio signal purity and precision even at low volume levels.
• Terrapin modules. Both the 851E and 851W use our proprietary
Terrapin impedance buffering modules, for absolutely consistent sound
across all sources.
• Toroidal transformers. The 851E and 851W both use a large toroidal
transformer to deliver perfect power, with extremely low distortion. The
851W takes things one step further by using two separate toroidal
transformers; one for the power amplifier itself and one for input and
other circuitry, for a performance unaffected by audio output volume or
dynamics.
When we set about developing our Azur 851 Series of hi-fi
separates, the brief was simple: to make a hi-fi system that
sounds better than anything else out there. The award-winning
851 series is designed with one goal in mind – perfection. With
this in mind, the Azur 851E and 851W are the ultimate pre and
power amplifier combination.
By separating out pre and power amplifier functionality, our
engineers were able to give each component the time and
dedication that it needs to deliver the ultimate performance.
The 851E pre-amplifier is an analogue pre-amp that is so
accurate, it’s almost impossible to detect audio distortion. In
fact, with every component designed not to interfere with the
audio signal input and output, harmonic distortion and noise are
so low that they’re almost impossible to measure.
The 851W power amplifier is our best ever sounding
amplifier. Key to this is a refined version of our proprietary
Class XD amplification. This combines the best of Class A and
Class AB amplification, delivering the sound quality of a Class A
amp while retaining the efficiency of a Class AB amp.
The 851E and W are, of course, designed to work in perfect
synergy with each other – from the fully balanced XLR audio
connectivity, to neat touches such as power syncing with each
other - this pre and power amplifier combination not only sounds
incredible, but works in perfect harmony too.
Top-Tips
The 851E is supplied with our new system remote,
allowing you to control the amp, CD, DAC and streamer,
all from the same remote.
