Description
With a three-stage inverted Darlington amplifier and great care taken in damping vibration, the Onkyo ICON M-80 power amplifier drives large speakers powerfully and delivers dynamic full-range sound that will captivate and move you.
Powering the music that moves you
The Onkyo M-80 Power Amplifier uses a three-stage Inverted Darlington Amplifier. This three-stage Inverted Darlington Amplifier has a very low output impedance and powerfully drives speakers with a large current. Additionally, by keeping NFB (negative feedback) low, it’s not affected by extra noise from the speaker, offering a powerful yet highly resolving and informative sound. The M-80’s output stage transistors are in parallel configuration, providing excellent instantaneous current supply capability, further enhancing the rise of sound and the sense of power. The driver stage of the M-80 amplifier uses DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) which reduces noise in the ultra-high frequency band with DIDRC’s High Slew Rate Design and helps produce the natural sound of an analog record.
Cutting-edge componentry, captivating playback
The Onkyo M-80 Power Amplifier features custom high current power supply to provide, dynamic full-range sound, and an extrusion aluminum heat sink that suppresses vibration. The addition of high-quality 10000uF capacitors custom-made exclusively for Onkyo, Hi-Fi grade terminals (both speaker output and audio input terminals), copper bus bars, and a robust vibration-proof front panel ensure powerful, world-class playback.
The M-80 housing consists of two aluminum side panels and a steel top panel. This three-piece housing construction increases rigidity and improves seismic resistance for altogether improved sound quality.
Create your perfect system
The M-80 has an output power of 130w(8Ω, 20Hz – 20kHz, THD 0.07%, 2ch driven) / 200w(4Ω, 1kHz, THD 0.7%, 2ch driven) which allows it to powerfully drive large speakers and bring you dynamic acoustic information. For example, Klipsch Forte speakers paired with the P-80 and M-80 would maximize the dynamic and extended sound of the Forte.
From Onkyo academy: 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 give you ultimate flexibility in audio playback. Furthermore, since they are not affected by each other’s circuits, they can provide high-resolution sound quality through even cleaner signal transmission. Audiophiles are well-known to prefer specific power amps and for the way they impact sound quality and coloration. 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.
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.
