The CXN is our fastest, slickest network player yet, and this is helped by the processing power of our bespoke new Cambridge Connect app. The app, which offers a new menu system plus a more graphical and intuitive interface, locates uPnP servers on your network, makes sense of the folder structure and lists content metadata, all without skipping a beat.
The CXN also supports C-BUS control, allowing power and volume to be controlled via the Cambridge Connect app. The CXN can be employed as a digital pre-amplifier, with volume control performed by the Sharc DSP; for maximum quality, this resamples at every volume step. Thereʼs also asychronous USB (24-bit/192kHz resolution) with DSD64 playback support. Using the app to find the track you want to play, not the player, results in a faster, more satisfying user experience. We believe this switcheroo is ingenious. Before, our streaming module would have to go find the uPnP servers and serve up the file structure back to the app - a relatively slow process. In the CXN ecosystem, your smartphone or tablet app handles all the browsing, searching and finding.
Naturally file playback support is wide, with all popular codecs and wrappers supported, including WAV, FLAC, ALAC, AIFF, MP3, HE AAC and AAC+ OGG Vorbis. UPnP media playback is joined by AirPlay, Spotify Connect and Internet radio.
Built to sound better
Just as with other components in the CX series, the CXN features a low-resonance, acoustically dampened chassis, allied to a high quality power supply - and for the first time on a Cambridge network player, thereʼs also a high resolution, full colour TFT display, which compliments the browsing experience on the Cambridge Connect app.
Unleashing Zander
With the CXN, weʼve been able to unlock more of our extremely powerful Zander audio streaming module. Incredibly, itʼs currently utilising only about 20 per cent of its potential. Expect firmware updates to unlock more features and functionality over time.
Dual Differential DACs
The two Wolfson WM8740 DACs within the CXN are used in a dual differential mode. Put simply, this means we use one stereo DAC per channel. Not only does this give us terrific stereo separation, but also enables us to multiply up and convert at 24-bit 384kHz (2 x192Khz) per channel. Why do we use Wolfson WM8740 DACs? Because they sound great, of course!
Adaptive Time Filtering upsampling
The CXN employs Cambridge Audioʼs proprietary 2nd Generation Adaptive Time Filtering (ATF2) upsampling technology, which is implemented in the CXNʼs Analog Devices Sharc DSP. Traditionally, upsampling algortithms consider two bits of data then draw a line between; our ATF technology considers both the data and its overall shape, then interpolates where itʼll best fit the waveform. We believe this is a more accurate, realistic way of handling audio upsampling, and results in a more convincing soundstage.
Bespoke Bluetooth
If you want to use the CXN with a Bluetooth source, we offer an optional BT100 audio receiver.
From the ground up, this is an audiophile Bluetooth device. All the coding for the BT100, from the XMOS interface to the aptX implementation, is done in-house. We even include an extension cable which enables you get the best Bluetooth range.

Enjoy stereo sound from CDs, CD-Rs, CD-RWs, data CDs, and compatible USB drives with the Silver Yamaha CD-S303 CD Player. It uses a 192 kHz / 24-bit digital-to-analog converter for detailed audio reproduction from the stereo RCA analog output, or you can use your own DAC via the optical or digital coaxial outputs. A remote control and stereo RCA cable are included as an added convenience.
Inheriting many of the sound quality features of the high-end CD player components, the CD-S303 CD player delivers sound that will satisfy devoted music fans. In addition to CDs, it also provides high-quality playback of music files stored on USB memory devices via a USB port on the front panel.
Yamaha technicians devoted a great deal of time and effort to designing the overall interior layout of parts and circuit boards, a factor that significantly affects sound quality. As a result, the power supplies for the motor drive, display, and USB sections, as well as the digital and analog sections, are individually isolated, eliminating electromagnetic interference among them. To achieve ideal weight balance for stable performance, the drive mechanism is located in the center of the unit.
The logical and symmetrical internal layout of parts and circuit boards are designed to keep the signal paths on each board as short as possible. This purposeful design also keeps the paths between sections straight and short, minimizing the chance of signal loss or interference.
The CD-S303 offers Pure Direct Mode, which is the same popular feature included in Yamaha amplifiers and receivers. By pressing the button on the front panel or on the remote control, it shuts down the digital audio output and turns off the display. This achieves the lowest possible noise interference and, therefore, the highest sound quality of the analog audio output.
Each of the individual elements in a CD player influences the sound quality, which is why Yamaha puts a great deal of effort into the selection and matching of parts and materials. A high-grade acoustic capacitor, a low-noise, high-gain bandwidth op amp, and the use of damping material under the transformer and around the signal cables are just a few examples of the Yamaha commitment to great sound quality.
Utilizing a 192 kHz/24-bit DAC, the high-performance D/A conversion system takes full advantage of the digital technology refined by Yamaha over a period of many years, ensuring excellent conversion precision, S/N ratio, and dynamic range.
The USB port on the front panel gives you an easy way to enjoy high-quality sound from MP3, WMA, LPCM, AAC, or FLAC digital music files stored on USB memory devices. You can also play files recorded on CD-R/RW discs.
The laser pickup is isolated on a floating mechanism so its delicate operation cannot be affected by vibration.
Conventional tracking servo circuitry cannot completely overcome errors caused by a warped disc, dust, and other defects. This system uses a dependable DSP, exclusive for CDs, to monitor the signal, adjusting pickup tracking and focus, as well as spindle motor speed, to compensate for any problems.
Information about the currently playing CD is shown right on the CD player's display. The 3-mode CD Text display shows the CD's title, the artist's name, and the title of the track.
It's easy to program the tracks you want to hear in any order. You can clear the program at any time with a single touch.

Key to the audiophile performance offered by the CXC CD transport is our S3 servo solution. The vast majority of optical drives in use today are designed with computers in mind. While they can read all manner of disc media, they lack the precision and finesse of a dedicated audio drive. To address this, we have written our own software to precisely control the driveʼs laser and motor assembly.
SIMPLIFYING THE SIGNAL PATH
The CXC is simplicity itself to setup and use, because we handle digital to analogue conversion in our amplifiers. Thereʼs a good reason behind this philosophy. Maintaining the audio signal in the digital domain for as long as possible minimises potential analogue signal degradation. Our CXC transport has one job to do and it does it very well indeed.
Our proprietary Cambridge S3 servo solution effectively turns a universal disc drive into a dedicated CD spinner; it can calibrate and monitor the speed of the disc, holding it steady and constant. By managing where the laser head is and what itʼs reading, as well as maximising error correction, we can get the maximum amount of clean data off the disc as possible, with the minimum jitter.
BUILT TO LAST
The CXC utilises a low-resonance acoustically damped metal chassis, with an ultra-clean low noise power supply. Beneath the hood, our PCB design employs double-sided surface mount technology, which eliminates wire links and ensures an ultra short signal path, thereby reducing signal deterioration.
C-BUS POWER SYNCING
Cambridge C-BUS connection means that one remote can be used to power on and off both CXC and CXA in sync.
