True High-Fidelity

This Onkyo stereo receiver features a powerful yet discrete 80-watt per channel low-impedance amplifier and an Asahi Kasei AK4452 digital-to-analog converter that delivers rich and clear 32-bit/384 kHz high resolution audio. Technical talk aside, the TX-8140 accurately reproduces all of your music from hip hop to heavy metal, experience every detail exactly as the artist intended.

Quality components
