Azur 651C CD Player

The 651C has the ability to retrieve maximum digital information so you hear every last detail from your discs


If you're after a way of extracting every last piece of data from your CDs and turning it into the most musical experience imaginable, then look no further than the all-new 651C CD Player. Developed to offer a true taste of high-end musical reproduction at an altogether more affordable price, it features an all-new twin Digital to Analogue Conversion system (DAC) with the same selectable filter arrangement used in the legendary DacMagic. These enhancements, in addition to completely retuned audio circuits, make for an even purer, more lifelike experience than its highly regarded predecessor.

Where many CD players use drives designed for computers, at Cambridge Audio we went the extra mile and created a CD-only S3 Custom CD ServoTM drive. This audiophile design gives the 651C the ability to retrieve maximum digital information which in turn means you hear every last detail from your discs.

A thousand words cannot convey just how lifelike the 651C sounds but a two minute audition at your nearest Cambridge Audio dealer will tell you everything you need to know!


In more detail...

Twin Wolfson WM8742 DACs deliver a significant performance upgrade over the 651C's award-winning predecessor and are implemented in a dual differential configuration (each channel has its own DAC to process information). A sophisticated Two-Pole Dual Differential Double Virtual Earth Balanced Bessel filter configuration rejects virtually all noise and distortion present in the DACs and filters them to produce an unprecedented level of performance.
The new DACs also feature a selectable digital filter with three settings to suit your own listening preferences and of course your own system:

The Steep roll-off filter exhibits strong attenuation of aliasing images outside the pass band (i.e. above 22.05kHz) at the expense of a little pre and post-ringing in the time domain.
The Linear phase filter uniquely features, constant group delay' which delays all audio signals at all frequencies by the same amount meaning all audio is fully time-coherent at the output.
Minimum phase meanwhile does not feature constant group delay but rather the co-efficients have been optimised without feed-forward so that the impulse response exhibits no pre-ringing in the time domain.


Cambridge Audio's CD-only S3 Custom CD ServoTM employs a custom designed chipset and the latest double-sided surface-mount technology for ultra short signal paths with freedom from wire links. Circuits and software have been meticulously designed and S3 dynamically adjusts focusing, tracking and output level of the laser in real-time, allowing for maximum retrieval of the digital information and jitter minimisation. This is all made possible by the implementation of a powerful ARM7 processor and complemented by a highly accurate master clock oscillator and carefully designed impedance-matched clock buffering scheme.


Meanwhile, the well-proven transport guarantees incredible rigidity and the CD drawer itself has been designed to offer a smooth, high-end feel. And to ensure simple operation, a high contrast reverse black DFSTN (Double Film Super Twisted Nematic) display offers excellent feedback of the 651C's impressive features which now include CD-text support.

As with all our Azur CD players, a high quality toroidal transformer ensures lower noise and less waveform distortion for quieter PSU operation.

Azur 651A Integrated Amplifier

The all new Cambridge Audio 651 will make all your music sound amazing


Thanks to the explosion in digital music, for many people the personal computer has become more important than their towering CD collections.

So we listened to you and instead of adopting the more common and simpler approach of including USB connectivity on a CD player, we've developed a direct USB audio connection to the 651A amplifier. So now, you can simply plug your Mac or PC directly into the 651A amplifier and with the addition of your chosen speakers, you'll instantly enjoy a whole world of digital music stored or streamed from your computer.

Computers are fast becoming a great addition to the hi-fi but they're not without their faults. Poor quality soundcards plus jitter - a side effect of digital music stored on computer hard drives - means audio performance can be really lousy. But plug your PC into the 651A and you'll be amazed just how incredible it sounds. Our in-house developed USB audio processor extracts audio data directly from your PC hard drive - bypassing its soundcard - and takes care of the critical digital to analogue conversion process bringing dull and lifeless MP3 files alive like you've never heard them before!


In more detail

toroidal transformer grid5

At Cambridge Audio we don't believe in gimmicks. Instead we like to invest in components that really make a difference to the sound you hear. That's why in the 651A, we use a premium toroidal transformer which is key to its unruffled performance with music of all types.

Adding to the audiophile specifications are separate transformer taps for left & right channels, twin rectifiers and separate PSUs for dual-mono operation of the left and right power amplifiers. Meanwhile a high grade film type volume pot means the 651A also performs as well at low levels as at higher volumes.

Whatever hi-fi speaker you choose, the 651A is designed to drive almost any model with ease. Our retuned output stage featuring Sanken output transistors gives excellent bass response and dynamic control.

We all like to crank up the volume from time to time and our proprietary CAP5 system ensures unrivalled peace of mind against overloads, faults and clipping.

Meanwhile, connection support for analogue sources like CD players, iPod docks and tuners is better than ever so whether you store or stream music from your computer, iPhone or maybe you prefer the luscious sound of good old vinyl, the all new Cambridge Audio 651 will make all your music sound amazing.


Class-leading power of 75 Watts per channel remains another massive advantage and a whole host of custom designed components together with our legendary approach to design means whatever you're listening to, it'll simply sound fantastic.

Concept 40 Speakers


The Concept 40 is Q Acoustics’ flagship floorstanding speaker. It is the newest addition of the acclaimed, award winning Concept range and, like so many Q Acoustics models, delivers an unparalleled sonic performance at its price. We firmly believe the Concept 40 sets new standards, even outperforming many speakers in higher price brackets.

In common with the Concept 20, its award-winning ‘little brother’, the new Concept 40’s extraordinary soundstage, dynamics and sheer musicality is achieved by incorporating its bespoke drive units into a ‘GelcoreTM Construction’ cabinet. This State-of-the-Art, ultra-low resonance and beautifully lacquered cabinet design allows the drive units to perform at their very impressive best.

The low distortion drive units incorporate powerful oversized magnets to ensure wide dynamics and an ultra-fast transient response. The elegant tripod stand allows the Concept 40 to achieve perfect rigidity and floor contact which further enhances its performance.

Even the speaker’s attractive aluminium facia plate is not purely decorative. It’s part of an assembly which clamps a butyl rubber sheet to the front panel to reduce cabinet resonance still further.

With 90dB sensitivity and a nominal impedance of 6 ohms, the Concept 40 is easily driven by any good quality amplifier. This striking floorstanding loudspeaker is available in either high gloss black, or high gloss white finishes.
