The Onkyo M-80 is a two-channel stereo power amplifier from the Icon series, rated at 130 watts per channel (FTC, 8Ω, 20Hz–20kHz, 0.08% THD) and 200 watts per channel into 4Ω. It uses a three-stage Inverted Darlington amplifier with parallel-configured output transistors and is offered in Black and Silver.
Why This Model Matters
Drawing on Onkyo's amplifier engineering since 1946, the M-80 is a purpose-built power stage designed to pair with the Icon P-80 network preamplifier. Custom 10,000µF capacitors, copper bus bars and a vibration-proof front panel focus the design squarely on clean, distortion-free power delivery.
