Sony PHA-3 Portable Headphone Amplifier / DAC
The Way The Artists Truly Intended
Enjoy the subtlest nuances of studio-quality sound in higher than CD quality with High-Resolution Audio. Passion for music unites every component from signal to speaker so it feels like the artist is performing right in front of you.
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-analog 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.
Pulse Code Modulation
Listen in the best possible sound quality through a variety of devices—PC, iPhone/iPad, and Xperia™ smartphone — with up to 384 kHz / 32-bit PCM encoding.
Direct Stream Digital
Hear the authentic, intimate detail of analog sound from your digital audio with Double DSD (5.6 MHz) and DSD (2.8 MHz) high-quality digital audio coding.
Ultra high frequencies
Feel sound beyond natural hearing with exceptionally high frequencies up to 100 kHz.
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 analog amplifier.
Made for High-Resolution Audio
With this separate USB DAC amp linking your headphones and a compatible PC, smartphone or Walkman®, you’ll enjoy higher quality High-Resolution Audio sound. The amp supports the very latest 384 kHz / 32-bit PCM and 5.6 MHz Double DSD formats.
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.
