Product Description

  • Excellent condition
  • Original box, packing and accessories

The PHA-2 Portable High-Resolution DAC and Headphone Amplifier from Sony allows you to play back high-resolution audio files, including PCM files up to 192kHz/24-bit and 2.8/5.6MHz DSD files from your computer or mobile device. It features a variety of digital inputs, including mini and micro-USB-B types for use with Sony's Walkman line, and a standard USB-A input for compatibility with iOS devices.

An aluminum housing helps protect the PHA-2, allowing it to be used on the go. The included silicone straps allow you to attach it directly to your portable device. Its built-in rechargeable battery provides up to 6.5 hours of life when used as a DAC and up to 17 hours when used solely as a headphone amplifier via its analog input. micro and mini USB-B cables are included, as well as a standard USB-A cable for charging.

Unlock Hi-Resolution Audio on the Go

The PHA-2 portable headphone amplifier allows you to playback high-resolution audio through your headphones. The PHA-2 can decode PCM audio sources at 192kHz/24-bit and DSD audio sources at 2.8 MHz / 5.6MHz formats

Flexible Connectivity

The PHA-2 is compatible with a wide array of digital devices. It has 3 USB inputs: standard A for iPod/iPhone/iPad devices, mini-B for hi-res Walkman and micro-B for PC or Mac. The PHA-2 also offers an analog input for connecting to most MP3 players, smartphones and other audio devices as well as a line out for external amp or active speakers

Jitter-Free Audio

The DAC features an asynchronous USB 2.0 clock that supports accurate DA conversions. The precision clock signal generator reduces timing inaccuracies when converting digital signals into analog waveforms. This maintains sound stage integrity and audio response, resulting in high-resolution audio performance with minimal noise and distortion

Amplification Circuits

The PCM1795 DAC samples PCM audio at 192kHz/24-bit & DSD audio at 2.8/5.6MHz. The LME49860 operational amp delivers signal & performance with low distortion, low noise & high slew rate. The high bandwidth TPA6120 headphone amp minimizes noise, delivering than 120 dB of dynamic range to ensure music is heard

Designed for Durability

The compact aluminum enclosure protects the delicate circuitry inside from outside interference and impacts while alloy bumpers protect the volume knob and headphone connectors from external impact. Recessed control switches reduce the chance of accidental access during playback

Flexible Headphone Support

A two position, side mounted gain switch allows you to optimize the PHA-2's output level to match varying headphone impedances from 8 to 600 Ohm

Rechargeable Lithium-ion Battery

The internal rechargeable battery provides approximately 6.5 hours of hi-resolution playback when connected digitally via USB input or up to 17 hours of playback when connected using the analog, 1/8" stereo input
