Sony PHA-3 Portable Headphone Amplifier

Created for Audiophiles and Pure High-Resolution Audio Performance: Sony PHA-3 Portable Headphone Amplifier Plays PCM and 2x DSD, Features DSEE-HX and Three USB Ports

Customized for high-resolution audio, the battery-powered Sony PHA-3 portable headphone amplifier supports 32-bit/384kHz PCM and 2x DSD (5.6MHz). It plays digital with the kind of clarity, dynamics, and richness that stir our deepest passions. Able to mine ultra-high-frequencies and upscale compressed files via DSEE-HX (Digital Sound Enhancement Engine), PHA-3 boasts a built-in high-bandwidth TI TPA6120 headphone amplifier that drives almost any 'phone. Plus, the aluminum-clad PHA-3's diminutive size means it's ready to travel at a moment's notice. Balanced audio outputs with dedicated left and right channels, tremendous capability with high-res players and cables, an analog input, three USB ports, and asynchronous USB performance also testify on behalf of PHA-3's do-it-all and do-it-well pedigree. 100% Music Direct Guaranteed.

Ready to Play High-Resolution Audio With Sterling Fidelity, DSEE-HX Upscaling
PHA-3 is able to reproduce almost all high-resolution audio formats such as DSD (DFF), DSD (DSF), WAV, AIFF, FLAC, and ALAC. Moreover, thanks to Sony's advanced DSEE-HX (Digital Sound Enhancement Engine), it upscales the existing sound source to near-high-res quality. This means you get maximum clarity and depth in your music, as PHA-3 refines and restores the audio signal to recreate the subtle high-frequency sounds typically lost in compressed MP3 and AAC files.

Balanced Audio Outputs With Dedicated L/R Channels
To give you a lively sound, PHA-3 features balanced audio outputs with dedicated left and right channels to deliver an optimized listening experience courtesy of a balanced terminal with independent amps. With increased driving force and significant noise reduction, your personal audio experience just got even better. Plus, thanks to a high-end DA converter that enables digital connection, PHA-3 faithfully reproduces the original sound as the artist intended. Enjoy the easy connectivity of amplifying your music no matter the input source, whether it's your smartphone, portable audio player, PC, or other analog devices.

Created for Audiophiles, Compatible With High-Res Players and 'Phones
Created for discerning audiophiles, PHA-3 comes with advanced technology tailored for the highest range of High-Resolution Audio headphones. The USB PCM 32-bit/384kHz for example, produces hyper-realistic and emotive sound that emulates a live performance.
