SoundGuy Posted May 12, 2017 Share Posted May 12, 2017 (edited) SOLD Item: Cambridge Audio Azur 851WLocation: Perth SouthPrice: $1900 Retail Price $3600 Item Condition: Brand New (only turned on to test it working)Reason for selling: Clearing StuffPayment Method: Pickup - Cash, Paypal, COD OnlyExtra Info: I bought this privately of a local guy here in Perth. Box was sealed and item was brand new. I only opened it to make sure everything works. Currently selling for $3600 everywhere: https://www.stereophonic.com.au/cambridge-audio-azur-851w-power-amplifier/ http://www.lifestylestore.com.au/cambridge-audio-azur-851w-power-amplifier.html https://klappav.com.au/products/851w?utm_medium=cpc&utm_source=googlepla&gclid=CjwKEAjwl9DIBRCG_e3DwsKsizsSJADMmJ11tP_LnKXKseFLs7ao93lQ48KNr1pg6h6FCxMwemxQNxoC1Hjw_wcB 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.

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

psychometrics1 Posted May 12, 2017 Share Posted May 12, 2017 FYI Frank Prowse HiFi in Perth has a black S/H CA 851 pre for about $900 that may interest a potential buyer (I have no connection re either item). 2 Link to comment Share on other sites More sharing options...
SoundGuy Posted May 12, 2017 Author Share Posted May 12, 2017 Thanks Kym. It can create a decent combo on the cheap ($900+$1900) :-) Link to comment Share on other sites More sharing options...

Actually its the previous generation 840E, not the current model. Link to comment Share on other sites More sharing options...
