    Sony PHA-1A Reviews

    PHA-1A Portable High-Resolution DAC and Headphone Amplifier is rated 4.5 out of 5 by 2.
    Rated 4 out of 5 by from Great Portable High-Resolution DAC and Headphone Amplifier I use the PHA-1A to play FLAC file 44-192kHz from Nexus 5 mobile phone and Samsung Tab-S tablet, both android. I use the USB Audio Player Pro application on both. I connect the PHA-1A to both devices with the supplied cable (Sony says very little on compatibility, seems the cable is micro-usb to micro-usb OTG) and use Grado or Sennheiser headphones. Both need the Gin switch in the 'high' position. The soubd is great dynamic and rich, but I have no comparable device... Cons: 1. You can not charge the device while play (despite having a different connector for charging). 2. You need to purchase the AC charger separately.

    Does this increase the sound volume or just clarity? Ill be using it with a pair of headphones with an impedance of 40 ohms 6-42,000 Hz.
    Asked by: Randy T.
    The Sony PHA-1A is a both headphone amplifier, giving you increased volume, as well as a DAC which will enhance the frequency response of your digital files.
