Powerful 165-Watt Class A Output with Superb Control

At the core of the MPA-4’s design is a high-power Class A amplification circuit, delivering 165 watts into 8 ohms to ensure every detail and nuance in the music is faithfully reproduced. This robust output allows the amplifier to effortlessly handle demanding musical peaks, maintaining clarity even at high volumes. The amplifier’s input sensitivity is optimised at 1 volt for full output, allowing it to pair seamlessly with high-quality pre-amplifiers, including Sugden’s Masterclass series, to create a comprehensive and balanced audio system.

Fully Balanced Mono Input for Enhanced Signal Purity

The MPA-4 features a dedicated balanced mono input, reducing noise and interference for a cleaner, more detailed signal. This fully balanced circuit architecture is crucial in high-performance systems, offering superior noise rejection and maintaining signal fidelity throughout the audio chain. This design choice ensures that every nuance is captured, providing a transparent listening experience free from distortion or colouration.

Extensive Frequency Range and High Signal-to-Noise Ratio

With a frequency response of +/-0.0dB from 15Hz to 30kHz and a wide bandwidth extending from 2Hz to 200kHz at -3dB points, the MPA-4 reproduces both high and low frequencies with impressive accuracy. Its high signal-to-noise ratio of over 85dB further minimises background noise, allowing subtle details and intricate textures within the music to be heard clearly. This extensive range and high SNR contribute to the MPA-4’s ability to convey rich, full-bodied sound with remarkable clarity and realism.
