Azur 851W 200 Watt Reference Power Amplifier

2 Year Exchange Warranty

FLAGSHIP POWER AMPLIFIER

The 851W has class XD amplification at 200W into 8 Ohms in stereo mode or 500W RMS per amp in mono bridged mode, separate toroidal transformers for the power amp and input/other circuitry, and terrapin impedance buffering modules. All in all it's the best sounding amplifier we have ever made.

PURE PERFORMANCE

Our best sounding amplifier ever, delivering a stunning 200 watts per channel. Works in stereo, mono or bridged mono mode for complete flexibility. Click on the video to the right to hear more.

CLASS XD AMPLIFICATION

Our proprietary amplification system switches dynamically between Class A and AB systems. Class A amplification delivers the purest possible sound, using only one transistor to conduct, but can be energy inefficient. Class AB involves both transistors conducting simultaneously, but makes it impossible to maintain a balance of low crossover distortion and power efficiency.

Our Class XD system operates in both Class A and Class AB mode, dynamically moving the crossover point depending on the audio output volume. This combines the near zero crossover distortion of pure Class A with improved efficiency of Class AB at higher volumes, without any compromises in performance for the best of both worlds.

TERRAPIN IMPEDANCE BUFFERING MODULES

These proprietary modules replace the op-amps commonly found in similar amplifiers. At the critical low level gain stages, these offer far improved stereo separation and imaging – this is very rare at this price point.

ALL METAL CHASSIS

Extensive use of aluminium creates massive structural rigidity, while careful damping and control of acoustic resonance contribute to audiophile sound quality. Click on the video opposite to find out why all of our products use metal chassis.

SYSTEM INTEGRATION

Smart auto-standby mode detects incoming audio signals providing seamless integration with our preamplifiers.
