M-80 POWER AMPLIFIER
Powering the music that moves you
With a three-stage Inverted Darlington Amplifier and great attention paid to vibration suppression, the Onkyo M-80 Power Amplifier powerfully drives large speakers to deliver dynamic full range audio that will captivate and move you.

Three-Stage Inverted Darlington Amplifier
The Onkyo M-80 Power Amplifier uses a three-stage Inverted Darlington Amplifier with very low output impedance that powerfully drives speakers with large current. By keeping NFB (negative feedback) low, it’s not affected by extra noise from the speaker, offering powerful yet highly resolving and informative sound. The output stage transistors are in parallel configuration, providing excellent instantaneous current supply capability.
DIDRC Technology
The driver stage uses DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) which reduces noise in the ultra-high frequency band with High Slew Rate Design. This technology helps produce the natural sound of an analogue record, enhancing the rise of sound and the sense of power.


Premium Components
The M-80 features a custom high current power supply, extrusion aluminium heat sink that suppresses vibration, and high-quality 10000uF capacitors custom-made exclusively for Onkyo. Hi-Fi grade terminals for both speaker output and audio input, copper bus bars, and a robust vibration-proof front panel ensure powerful, world-class playback.
Superior Construction
The M-80 housing consists of two aluminium side panels and a steel top panel. This three-piece housing construction increases rigidity and improves seismic resistance for altogether improved sound quality and exceptional vibration suppression.

Benefits of a Power Amplifier
A power amplifier receives the signal from your pre-amp and literally powers it into your speakers. Think of your pre-amp as a brain, and your power amplifier as the muscle. Separating your amplifiers into pre- and power gives you ultimate flexibility in audio playback with cleaner signal transmission and high-resolution sound quality.
Powerful Performance
With an output power of 200w (4Ω) / 150w (8Ω), the M-80 powerfully drives large speakers and brings you dynamic acoustic information. For example, Klipsch Forte speakers paired with the P-80 and M-80 would maximise the dynamic and extended sound of the Forte.
ICON SERIES
The Icon series, developed to be the icon of the Onkyo brand, is not only a renewal of Onkyo’s previous Hi-Fi products but the culmination of Onkyo’s accumulated and continuously evolving sound creation technologies. The M-80 is a power amplifier that reproduces the full range of artists’ intentions in their music and drives you into a world of emotion.
