INTEGRATED AMPS AND CD PLAYERS
Cambridge Audio's calling card has always been its wonderfull integrated amps so it surprised no one that
when the Azur 840A was introduced it broke the mould by introducing an entirely new class of amplifier design in the shape of Class XD™ and marked the zenith of Cambridge Audio’s critically acclaimed Azur line-up. The 840A V2 now embraces the second generation of Cambridge Audio’s patent pending proprietary technology and has employed some subtle but significant updates to improve upon this already outstanding design. The second generation Class XD is now complemented by a new output stage carefully adjusted to integrate with this novel technology, revised balanced inputs for lower distortion and noise and a new more accurate volume control with even lower crosstalk for greater stereo imaging.
At the core of the 840A’s strength is a patent pending, Class XD (crossover displacement) technology which has been subtly revised following continuing post-launch development and critical evaluation. This unique design gives pure Class A operation at low levels, moving smoothly into an enhanced version of Class B at higher levels. This system should not be confused with Class AB, which inherently generates greater distortion at high levels than a pure Class B design. XD technology feeds a controlled current into the output stage actively displacing the crossover point in a new way so that the usual Class B crossover point no longer occurs at zero volume - the worst possible position in terms of distortion – but at a significant output level. The result is a smooth and linear transition between the two modes of operation, which differs significantly from the abrupt, gain transition of a Class AB amplifier.
The Azur 840A amplifier includes a massive, oversized low flux toroidal transformer, incorporating a silicone-steel screen. To separate the delicate signals needed by the pre-amp from those needed by the power-amp, the 840A features a completely separate pre-amp toroidal transformer, mounted to the rear casework.
In addition to this innovative technology, the 840A also uses an extremely sophisticated resistor ladder / relay attenuator with gold-plated contacts for volume and balance control. This gives extremely low distortion with superb channel balance and incredibly accurate control in 1dB steps over the whole range.
The technological breakthroughs incorporated into the 840A has trickled down into all the integrated amps sothat now more than ever cambridge amplifiers represent remarkable performance for the money- ranging in price from $500.00 on up.
What would a great integerated be without a great cd player.?
Fortunately?,cambridge makes these in abundance .Take the 840C!
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.As with the 840a the breakthroughs learned in designing the 840C have trickled down into all the Cambridge audio Cd Players .So, now from $500.00 on up Cambridge makes just the right player for you.
