Cambridge Audio EXA100, integrated stereo amplifier

The EX integrated amplifier EXA100, which is the heart of the EX, has been three years in the making; over a thousand days of tuning at our headquarters in London has resulted in a massive increase in power and performance for the CX series amplifiers.

 

Boosted by trickledown technology from our flagship Edge M monobloc power amplifier, EXA100 uses its 100W of beautifully refined Class AB amplification to drive even high-end speakers with ease.

Back in the Summer of Love, our P40 amplifier was the very first to feature a toroidal transformer – and transformed audio forever.

EXA100's advanced toroidal transformer is amply shielded, super-quiet and flanked by heavy-duty heat sinks for impeccable performance that's more than worthy of extending the P40 legacy.

The EXA100 lets you listen how and wherever you want, in sublime quality. Balanced XLR inputs offer a premium analogue connection, while two sets of speaker outputs can power music in two different rooms.

Bass-heads can even add a subwoofer to the dedicated pre-out. With EX, you get a world of listening possibilities.

From its exceptional hi-res DAC to the HDMI eARC input and Bluetooth aptX HD, EXA100 is a digital audio powerhouse. Whatever music service or source device you choose, EXA100 will breathe new life into your digital sounds.

Our innovation doesn't stop on the inside: the EXA100 has a stunning new design, complete with a milled aluminum front panel and a tactile knurled volume knob you can't keep your hands off.

This jaw-dropping amp looks as powerful as it sounds.

Switch it to Power Amp Mode and the EXA100 pairs brilliantly with any pre-amp, giving flexibility you never knew you needed – whether in a stereo or multi-channel system.

To ensure a longer, happier listening life for our amps and the speakers they power, we developed an exceptional proprietary protection system, CAP.

It uses an array of different methods to detect potential issues, such as power and temperature overloads, and take preventive action. So you can just relax and enjoy the music, worry-free.

From its precision build to the technology inside, the EXA100 is gloriously over-engineered. Whether it's a four-layer PCB or a reservoir capacitor, every component is specially selected and expertly implemented. We sweat the small stuff; it matters.
