The Cambridge Audio EXA100 Integrated Stereo Amplifier delivers pure sonic fidelity with its Class AB amplification. Its innovative design and engineering ensure a seamless connection to high-end speakers and a variety of audio sources.
The EXA100 employs a powerful Class AB amplification topology that balances the linearity of Class A with the efficiency of Class B, providing 100W RMS into 8 Ohms. This design minimizes harmonic distortion to less than 0.002% while delivering impressive power, enabling the amplifier to drive demanding speakers with precision. The shielded toroidal transformer provides low electromagnetic interference and enhanced power intake, while heavy-duty heat sinks ensure thermal stability during extended use. Furthermore, a meticulously designed four-layer printed circuit board reduces signal interference, preserving audio purity and ensuring high bandwidth performance up to 40 kHz, allowing for a rich listening experience across all frequencies. The high-quality DAC, capable of processing resolutions up to 384 kHz, partnered with features like Bluetooth aptX HD and a digital audio processing pathway based on asynchronous USB, makes it adaptable to modern playback needs.
