AUDIRVANA PLUS USB DAC FULL
This means that if you use the PHA-2 as your PC’s DAC you need to turn the volume to “off” at the end of the day if you want to have a full charge for the next day’s playback. Recharging the PHA-2 can only occur while it is not playing music.

If used as a DAC/headphone amplifier the figure will be the lower number if used solely as a headphone amplifier you can expect battery life to be closer to the 15-hour figure. Resetting the audio preferences in Audirvana Plus quickly solved this minor glitch.īattery life on the PHA-2 is spec’d from 7 to 15 hours. Occasionally, when going from DSD material to WAV on my Mac, I could “trick” the PHA-2 into spitting out noise instead of music. The only “tricky” part was selecting the right position for the PHA-2’s digital-input toggle switch.
AUDIRVANA PLUS USB DAC PORTABLE
With all the portable and computer playback devices I tried with the PHA-2 setup was virtually plug-and-play.
AUDIRVANA PLUS USB DAC DRIVERS
The PHA-2 employs an asynchronous USB 2.0 transfer mode that uses a proprietary driver for Windows no drivers are needed for Mac.

Sony’s technical literature notes that DSD 5.6 is not available for the Mac, and using Audirvana Plus 128x material is automatically converted to 176.24 PCM for playback. The PHA-2 DAC section supports a wide variety of digital formats including PCM up to 192/24, and DSD 2.8 (64x), and DSD 5.6 (128x) via any of its digital inputs. During the review period I used the PHA-2 tethered to a variety of devices including an iPhone 5 (via direct-digital lightspeed-to-USB connector), the Astell&Kern AK100 (via the analog input), the Astell&Kern AK240 (via analog), and several of my Macs via micro-USB. Whether you’re using the PHA-2 as a DAC or as a headphone amplifier, Sony assumes that any device you hook up to the PHA-2 will have its own navigation and playback controls. If you’re looking for a mute button or any way to navigate through a music library, you won’t find it on the PHA-2. On the bottom of the PHA-2 you’ll find three digital inputs as well as a small toggle to select which one is currently active. The other LED glows red during recharging. Three blinks signify a full charge, two a partial charge, and one blink means you don’t have much time before recharging will be needed. The “power” LED glows green when the unit is playing and also tells you the charge level of the internal rechargeable 3.7-volt 2160mAh Li-ion battery via a series of blinks when you initially turn it on. Next to the volume knob are two small LEDs. One side of the PHA-2 has a pair of toggle switches to select between the line-level and headphone outputs and to choose the normal or high-gain amplifier-output levels.Ĭontrols on the PHA-2 include a large volume knob, nestled underneath one of the alloy bumpers, that also turns the unit on and off. Outputs include one mini-stereo headphone output plus the line-level. The PHA-2 also accepts analog via a mini-stereo input that doubles as a line-level output.
AUDIRVANA PLUS USB DAC PC
It has provisions for digital inputs from a PC via a micro-USB, or an iPad/iPhone/iPad via a standard USB, or a high-resolution-supported Walkman via Sony’s own proprietary mini-USB connector. The 270-gram (.6-pound) PHA-2 is housed in an aluminum enclosure that features a zinc alloy bumper as well as a unique rail/edge design. For the on-the-go audiophile who wants to own and carry only one DAC/headphone amplifier on his travels, the Sony PHA-2 could be just what the traveler ordered. The Sony PHA-2 portable headphone amplifier and DAC was created to be a digital “bridge” product, designed to improve the sound from smartphones, iPods, iPads, and computer USB sources. It proved to be an outstanding value that has shaken up the digital-audio-player marketplace. As part of its “high-resolution initiative” Sony has rolled out several exciting new products during the past year including the HAP-Z1ES and HAP-S1 digital players, the NW-F887 portable player (Asia only), and the PHA-2 portable DAC and headphone amplifier.
