Cambridge Audio EXA100 — Modern Muscle, Refined

Developed over three years as the beating heart of the EX series, the EXA100 delivers
100 W per channel of refined Class-AB power (155 W into 4 Î©) with the composure and
control to drive demanding loudspeakers. Its architecture takes cues from the flagship
Edge M monoblocks and is anchored by a heavily shielded toroidal transformer flanked by
oversized heat sinks for ultra-quiet, stable operation. A milled aluminum front panel and
tactile knurled volume knob complete a design that looks as confident as it sounds.

Highlights

  • 100 W/ch Class-AB (155 W/ch into 4 Î©) with Edge-inspired output stage and high current delivery.
  • Hi-res digital core with ESS ES9018K2M DAC, HDMI eARC, asynchronous USB, dual optical and coaxial S/PDIF.
  • Wireless in hi-def via Bluetooth 5.0 with aptX / aptX HD.
  • Analogue done right: balanced XLR plus four RCA inputs; pre-out and dedicated subwoofer output.
  • Flexible system building with dual speaker outputs (A/B), headphone output, RS-232 control and a dedicated Power Amp Mode for integration with AV processors or external preamps.
  • Engineered for purity: four-layer PCB layout, reservoir capacitor bank for deep, dynamic power, and heavy-duty heat sinks for long-term reliability.
  • Smart protection from Cambridge’s CAP system, continuously monitoring power and temperature to safeguard the amp and speakers.
