Cambridge Audio EXA100 100W Integrated Amplifier, Class AB, ESS DAC, eARC

The Cambridge Audio EXA100 is a 100W Class AB integrated stereo amplifier from Cambridge Audio's EX Series, designed and tuned at the company's London headquarters over three years of dedicated development. It delivers 100 watts per channel into 8 ohms and 155 watts into 4 ohms, with technology inherited from the flagship Edge M monoblock power amplifier.

At its core is a custom audio-grade shielded toroidal transformer, continuing a legacy that began with Cambridge Audio's original P40 amplifier in 1968, the first hi-fi amplifier to feature a toroidal design. Heavy-duty heat sinks, a four-layer printed circuit board for signal purity, and a specially selected reservoir capacitor for deep, consistent power delivery complete the analogue amplification stage. ProHiFi is an authorised Cambridge Audio dealer in India.

The EXA100 also handles digital sources with a built-in ESS ES9018K2M SABRE32 DAC, supporting USB audio up to 24-bit/384kHz and DSD 256, HDMI eARC for TV audio, two Toslink optical inputs, one coaxial digital input, and Bluetooth 5.0 with aptX HD. A balanced XLR input, four RCA analogue inputs, a dedicated subwoofer output, a headphone output, and two sets of speaker terminals round out the connectivity. A Power Amp mode allows the EXA100 to function as a pure power amplifier when paired with an external preamp.

The Ear gave it a Best Buy, calling it "formidable." AV Forums awarded Best in Class, praising its superb tonal quality. Stereonet gave it an Applause Award, calling it one of the best integrated amplifiers in its class. Forbes, TechRadar, and What Hi-Fi have all covered the EX Series positively.

Why Consider the Cambridge Audio EXA100

The EXA100 is the right choice for listeners who want a refined, well-built British integrated amplifier that handles both analogue and digital sources at a high standard without requiring separate components. The Class AB amplification stage inherits engineering from Cambridge Audio's flagship Edge M, and the built-in ESS SABRE32 DAC, HDMI eARC, and Bluetooth aptX HD mean every modern source, from turntable to TV to phone, connects natively. Two sets of speaker terminals allow music in two rooms, the subwoofer output extends low-frequency capability, and Power Amp mode opens integration into larger systems. For an Indian audiophile comparing integrated amplifiers at this level, the EXA100 offers a rare combination of analogue refinement and digital versatility in a single, well-reviewed chassis.

Ideal for

• Listeners wanting a single amplifier for turntable, CD, streaming, and TV audio
• TV setups needing HDMI eARC for lossless audio from a smart TV
• Those upgrading from a CXA81 or similar mid-range integrated amplifier
• Systems requiring balanced XLR input for cleaner source connection
• Multi-room setups using dual speaker output terminals
• Installations needing Power Amp mode for external preamp integration
