The Cambridge Audio 840C is the companies statement CD player, pitched at a price that is firmly mid-priced but designed to achieve high-end status. Certainly when you buy in to a Cambridge Audio product like the 840C you are not only getting exceptional value but some rather clever engineering. In fact the 840C’s technical abilities for the price are outstanding; ponder over the rigidly constructed optical mechanism, marvel at the 16-bit 44.1 kHz CD data to 24-bit 384kHz upsampling and don’t forget the 15 stages of regulated power supplies, DC servo circuitry with no capacitors in the signal path. The auction is for the modification only and does not include the Cambridge Audio Azur 640C CD player which must be purchased separately.

So when it comes to fighting of the competition how does its fair? Well at 800 pounds sterling there is little or nothing to touch it at the price, but spend £300 - £400 more and it starts to get a bit out of its depths. In a recent magazine review it came second place in a £1000 CD super test.

Despite its superb engineering and sophistication it is not all things to all men, accused of sounding possibly boring, the 840C never quite manages to stir enough excitement and can sound lacklustre, softly defined, and vague around the edges. While the bass quantity is aplenty it is at times ponderous, even bloated.

With such technology, there are masses of untapped sound to be had from the 840C’s clever circuits. Rid the player of its dozens of general purpose capacitors, replace the stock oscillator with an ultra-low jitter clock partnered with a dedicated power supply and revamp the analogue filter & line stage and the player catapults forward in sound and slipstreams way ahead of the competition.

Audiocom have the recipe to transform the 840C into a stunning CD spinner. We have 2 levels of modifications, the level-1 upgrades installs 25 new components including the Superclock 4-S ultra-low jitter clock, Black Gate NX de-coupling capacitors & LM4562 op-amps for the line buffer stage. The more comprehensive level-2 upgrade installs 76 new components that include the Superclock 4-S ultra-low jitter clock, dedicated Superclock 4 ultra-low noise clock power supply, the superb LM4562 op-amps for the analogue filter and line output stage, Black Gate  NX &N DAC de-coupling, DAC reference /filter capacitors, etc.
