Accuphase A-80 Class A Stereo Power Amplifier

The A-80 is a Class A power amplifier developed as a stereo amplifier version of our 50th anniversary A-300 model. Optimizing the 10-parallel push-pull power MOS-FETs in the output stage produces an output power of 65 W into 8 ohms, 130 W into 4 ohms, 260 W into 2 ohms, and 520 W into 1 ohm. Rigorous investment into new, cutting-edge noise reduction technologies has achieved a sense of presence and minute expression that rival live performances. The A-80 power amplifier perfectly fuses modern technology with the wealth of knowledge Accuphase has amassed in its pursuit of perfect sonic expression. 65 W into 8 ohms, 130 W into 4 ohms, 260 W into 2 ohms, and 520 W into 1 ohm large linear output power Class A driven 10-parallel push-pull MOS-FET output stage Instrumentation amplifier Signal input section with a fully discrete configuration for low noise Current feedback amplification topology Balanced remote sensing MCS+ circuitry High damping factor of 1,000 Large, high-efficiency
