Accuphase A-80 Class A Stereo Power Amplifier

Accuphase A-80 Class A Stereo Power Amplifier

The A-80 stands as a pinnacle Class A power amplifier, born from the lineage of our esteemed 50th anniversary A-300 model. By meticulously refining the 10-parallel push-pull power MOS-FETs in the output stage, it delivers exceptional power output: 65 W into 8 ohms, 130 W into 4 ohms, 260 W into 2 ohms, and an astounding 520 W into 1 ohm. Through relentless innovation in noise reduction technologies, we've achieved a level of presence and nuance that rivals the authenticity of live performances. The A-80 power amplifier seamlessly integrates modern advancements with Accuphase's wealth of expertise, resulting in sonic excellence beyond compare.
