Onkyo A50B Icon Integrated Amplifier

The Onkyo A-50 Icon Integrated Amplifier is engineered to deliver powerful, refined stereo performance with exceptional clarity and minimal distortion. Built with premium components and vibration-resistant construction, this amplifier forms the heart of a high-performance two-channel hi-fi system.

The new Onkyo Icon Series blends modern hi-fi engineering with a clean, timeless design built for serious listening.

At its core is Onkyo’s Inverted Darlington Amplifier design, providing strong current delivery with precise control, while DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) ensures smooth, detailed sound reproduction even with complex digital sources. Combined with a premium DAC and carefully engineered chassis construction, the A50B is designed to reproduce music exactly as the artist intended.
