After a long wait, Cambridge has finally released their new EX line, which includes the Cambridge Audio EXA100 integrated amplifier. According to Cambridge, the EXA100 is more like the amplifier in their costlier EDGE M series, it uses a similar Class A/B design and has similar features. Many audiophiles have been eagerly waiting for the launch of this amplifier. After reviewing it, I can definitely see why people were waiting for this, but I also have some issues with this amplifier.
Review
The Cambridge Audio EXA100 is a Class A/B type amplifier that offers 100 watts per channel at 8 ohms, and 155 watts per channel at 4 ohms. It has a frequency response of 3 HZ – 40 kHz. Its front panel is made of Aluminum, and it has a volume knob and input buttons. You can also set the EXA100 to a Power Amp Mode, so it can be used with any preamplifier.
Unlike the M series, the EXA100 is an all-inclusive integrated amplifier with both analog and digital inputs. It has a built-in DAC with an ESS ES9018K2M chip. The DAC handles hi-res music and DSD files, and it supports Bluetooth 5.4 with aptX HD. Sadly, the EXA100 doesn’t have any support for streaming services or an app. This is probably a strategy to maintain sales of Cambridge’s dedicated streamers.
The Cambridge Audio EXA100 has four analog inputs, one of which lets you choose between balanced and unbalanced connections. It has two sets of five-way binding posts, a pair of pre-amp outputs, and a dedicated subwoofer output. Two notable omissions are a built-in phono preamp and a built-in bass management system. In terms of digital inputs, you have optical, coaxial, and USB. It also has HDMI eARC, a feature missing from the costlier C series amplifier. Because it has no streaming support or app, the setup is fairly easy and short. Once you connect your streamer and analog or digital sources, you’re done.
The Marantz Model 60n was one of the best amplifiers released this year, and I used it as my reference amplifier during testing with the EXA100. The EXA100 offers a noticeably better richer sound, and the overall sound is fuller. The low-end sound was clear and precise, and the bass and lower midrange were controlled and detailed.

Verdict
The Cambridge Audio EXA100 is an impressive addition to the EX line, offering a rich, full-bodied sound with exceptional clarity and control, particularly in the bass and lower midrange. Its robust Class A/B design and versatile connectivity options, including HDMI eARC and a high-quality ESS DAC, make it a strong contender in its price range. However, the lack of streaming support, an app, and built-in features like a phono preamp and bass management feels like a missed opportunity, especially given the competition. Despite these omissions, the EXA100 delivers where it matters most: sound quality. For audiophiles seeking an integrated amplifier with premium performance and no-nonsense functionality, the EXA100 is well worth considering—provided you’re willing to pair it with external components for a complete setup.
