Azur 840C CD Player & DAC

The 840C marks the zenith of Cambridge Audio’s critically acclaimed Azur line up.

Like all Azur products, the 840C promises unseen levels of performance and engineering excellence to the price points in question. But rather than redefining expectations in the entry-level market, the arena most often associated with Cambridge Audio, the company will reinvigorate the mid-end price sector.
 
The 840C embraces a raft of proprietary technologies including ATF™ (Adaptive Time Filtering) asynchronous up-sampling technology which has been developed in conjunction with Anagram Technologies of Switzerland. This system intelligently interpolates 16-bit/44.1kHz CD data to 24-bit/384kHz data, through the use of a 32-bit Analog Devices Black Fin DSP (digital signal processor). This in turn feeds two 24-bit/384kHz DACs from the same company in dual differential formation.
 
Each DAC handles just one channel for excellent stereo imaging, operating fully in differential mode for exceptionally low distortion and noise.
 
Both unbalanced RCA and balanced XLR outputs are fitted. Two digital inputs are also provided which even allow the up-sampling and playback of other sources such as a DVD player via the Azur 840C. In addition, a recording digital output can even allow bit-for-bit data or upsampled data at 48, 96 or 192 kHz to be recorded by a suitable device.
 
A Control Bus In/Out, an IR emitter in connection and an RS232 port are provided for easy multi-room connectivity. The RS232 protocol enables a two-way interface with third party home automation touchscreens.
 
As with all Azur products, the foundation of the 840C’s excellence is a bespoke chassis. This comprises an incredibly thick 7mm front panel and extruded side panels, both fashioned from aluminium, which combines with a 2mm formed steel base plate and specially designed vibration absorbing feet. The result is an ultra rigid, low resonance, acoustically dampened platform for the electronics to sit in.

Escala de classificação

Novo – Item lacrado na caixa.

Demo – Item tirado da caixa apenas para demonstração aos clientes pela equipe da HIFICLUB. Não foi utilizado ou manuseado por clientes. O item está em perfeito estado estético e de funcionamento. Não sofreu qualquer reparo ou modificação. Usado como demo pelo tempo máximo de 3 meses.

9/10 – Item praticamente novo e com pouco uso. Estado geral excelente. Item em perfeito funcionamento. Não sofreu qualquer reparo ou modificação.

8/10 – Item em muito bom estado. Numa vistoria minuciosa, é possível encontrar alguns detalhes estéticos, como sutis marcas de uso. Pode apresentar um pequeno risco, mas, nunca em áreas mais visíveis do item, como a parte da frente de um aparelho ou caixa de som.

7/10 – Item em bom estado. É, visivelmente, um item usado, porém, bem cuidado. Pode ter marcas ou riscos, no entanto, nunca em áreas mais visíveis.
