A Purer State of Sound

Feel Emotion in Every Note

The Science Behind the Sound

In the pursuit of pure sound quality, the PHA-1A is integrated with Sony’s innovative technologies: equipped with the Wolfson WM8740 DAC chip that is utilised for high-end premium models, a low-distortion amplifier that operates at a low-noise level, a high 5V power supply offers a high S/N ratio, and an output capacitor-less (OCL) amplifier ensures minimal sound distortion. High sound quality solder used in the Walkman^® NWZ-A17 delivers natural balances in low-mid-and high-range sound. This makes what you listen to closer to the original recording with more life in every note
