Sony PHA-3 USB DAC Headphone Amplifier

Enhance the quality of everything you listen to

Enjoy more authentic sound from your High-Resolution Audio and MP3 music

Hear sound that’s closer to the original recording. This USB digital-to-analogue converter (DAC) and headphone amplifier takes over from your PC or mobile device’s built-in amp. Original digital audio – including High-Resolution Audio – is processed by the PHA-3, creating a dramatically superior soundstage for enhanced listening.

Superior conversion, purer sound

Most portable devices include a simplified DAC converter, resulting in slightly compromised sound quality. This dedicated USB DAC amplifier takes over processing from your device, then amplifies sound for headphone listening using a custom-tuned, precision analogue amplifier.

Two micro USB inputs and charge port

Get connected. Hook up your PC, selected smartphones, or Apple iOS device with two Micro USB inputs, and charge while you listen with a dedicated micro USB port.

Stereo and balanced audio output

Listen through the stereo jack, or connect with a balanced audio cable – left and right outputs ensure authentic, even sound.

Optical input

Connect to HDD and SACD players with an optical connecter, supporting up to 192Hz/24bit PCM input.

Go beyond CD quality. Upscale MP3, ACC, ATRAC, and WMA music files

DSEE HX upscales compressed digital music by restoring the subtleties lost in compression. The result is rich sound, closer to the quality of High-Resolution Audio.

Balanced audio. Superior sound with a supplied balanced cable

Enjoy clear, precise, dynamic sound with a balanced cable. Two audio channels, each with an independent ground wire, use an inverted phase signal to reduce unwanted noise that is picked up as the signal passes through the wire from source to amplifier. The result – superior sound, delivered with clarity.
