The EXN100 is a network streamer and streaming DAC preamplifier, which means it is the "brain" of a modern music system that pulls in music from the internet and your home network and sends it onward to be amplified. Cambridge Audio is a British company with a long history of making music gear that focuses on sound quality and thoughtful design, and the EXN100 sits in their EX series, a step up in their lineup. In plain terms, it takes music from streaming services or your own files, converts that digital information into a clean audio signal, and hands it off to an amplifier and speakers.
Where does it fit in my system?
The EXN100 sits between your music sources and your amplifier. It does not have speakers built in and it is not a full amplifier that powers speakers on its own, so you will pair it with a power amplifier (or a pair of active speakers that have amplification inside them). The flow looks like this: streaming services and digital sources go into the EXN100, the EXN100 processes and controls the sound, and then it feeds an amplifier that drives your speakers. Think of it as the control center and translator for your music.
Understanding the Core Job: Streaming and Sound Conversion
What does "network streamer" actually mean here?
It means the EXN100 connects to the internet and your home network so you can play music without a CD or a turntable. It supports the big streaming platforms directly, including Spotify Connect, Tidal Connect, Qobuz, Amazon Music, Deezer, and Internet Radio, plus AirPlay 2 and Chromecast built-in for sending audio from your phone or computer. It is also Roon Ready and works with UPnP, which are ways of organizing and playing music stored on your own devices. In everyday use, you open an app, pick a song, and it plays.
What is a DAC and why does it matter?
A DAC (digital-to-analog converter) turns the ones and zeros of digital music into the analog signal your amplifier and speakers can actually play. The EXN100 uses an ESS ES9028Q2M chip from the SABRE32 Reference family, which is a well-regarded converter known for clean, detailed sound. This matters because the quality of the DAC has a direct effect on how natural and clear your music sounds. A good DAC helps voices and instruments come through with more realism and less digital harshness.
What music formats and quality levels can it play?
It can play just about everything, from everyday compressed files to very high-resolution audio. It handles PCM up to 768kHz/32-bit and DSD512, which are extremely high-resolution formats, along with MQA. It also plays common file types including ALAC, WAV, FLAC, AIFF, WMA, MP3, AAC, and OGG. In day-to-day listening, this means you never have to worry about whether your music will play. Whether it is a standard streaming track or a studio-quality high-resolution download, the EXN100 is ready for it.
The Connections: Inputs and Outputs Explained
What can I plug into the inputs?
You can connect a range of digital sources, though not analog ones like a turntable directly. The inputs include USB-B (asynchronous, handling up to 768kHz/32-bit and DSD512) for connecting a computer, a USB-A port for media such as a drive of your own files, coaxial S/PDIF and optical TOSLINK for other digital devices, and HDMI ARC/eARC (up to 192kHz/24-bit) so you can connect a television and enjoy your TV sound through your main speakers. There is no analog input, so everything coming in is digital. This keeps the signal path clean and lets the EXN100 do the conversion work with its own high-quality DAC.
How does the Bluetooth work?
The EXN100 has Bluetooth 5.0 with aptX HD, which lets you play music wirelessly from a phone, tablet, or laptop. The aptX HD part means it can stream Bluetooth audio at higher quality than basic Bluetooth, so casual listening from your phone sounds better than you might expect. It is the easy, grab-and-go option when you just want to play something quickly without opening a dedicated app.
What do the outputs let me connect to?
The outputs let you send sound to an amplifier and, if you want, to another digital device. You get unbalanced RCA and balanced XLR line outputs for connecting to a power amplifier, plus coaxial and optical digital outputs for passing the digital signal to something else. Balanced XLR connections are often preferred in higher-end systems because they help reject noise over longer cable runs. Note there is no headphone output and no dedicated subwoofer output, so the EXN100 is designed to feed a proper amplifier and speaker setup.
Control and Everyday Use
How do I actually control it day to day?
You control it mainly through the StreamMagic Gen 4 app, which is Cambridge Audio's own control app for browsing, selecting, and playing your music. The app also includes a 7-band EQ, which lets you gently adjust the tone (for example, adding a little more bass or softening the treble) to suit your room and taste. Because the EXN100 is a preamplifier, it also controls volume, so you manage everything from listening levels to source selection in one place.
What does the display show me?
The EXN100 has a 4.76 inch IPS TFT screen with a 1280 x 569 resolution, which shows things like album artwork, track information, and what is currently playing. A clear, colorful display makes the unit pleasant to use across the room and adds to the sense that you are interacting with a premium piece of equipment. It gives you useful information at a glance without needing to reach for your phone every time.
Build Quality and Design
Why does Cambridge Audio build quality matter?
Cambridge Audio has a reputation for careful engineering and solid construction, and that shows in how a component like the EXN100 is put together. The unit measures 430 x 90 x 305 mm (16.9 x 3.5 x 12.0 inches) and weighs 4.1 kg (9 lbs), giving it a substantial, well-made feel that fits neatly onto a standard shelf or rack. It comes in a clean Lunar Grey finish. Good build quality matters because it helps protect the sensitive electronics inside from interference and vibration, both of which can affect sound, and it means the component should hold up well over years of use.
Who It Suits
Is the EXN100 right for me?
The EXN100 suits anyone who wants a single, high-quality hub to bring modern streaming into a serious two-channel system. It is ideal if you already have (or plan to add) a good power amplifier and speakers and want a source and preamplifier that handles streaming, high-resolution files, and even your television audio through HDMI ARC/eARC. It is a great fit for someone moving up from an all-in-one system or a phone-and-speaker setup who wants noticeably better sound and room to grow. If you specifically need a headphone jack, a built-in amplifier for speakers, or a turntable input without extra equipment, keep in mind the EXN100 focuses on streaming and preamplifier duties instead. For the right listener, it offers a clean, capable, and future-ready heart for a high-end system, backed by Cambridge Audio's design and engineering.
