Hi-Res Support for iOS and Android
To experience 192 kHz/24-bit Hi-Res Audio and native 5.6 MHz DSD playback via iPod touch®, iPhone®, iPad®, or Android, download our free HF Player app and connect the DAC-HA300 to your iOS device via a Lightning cable or Android mobile using an On-the-Go cable. As well as enabling Hi-Res Audio via direct-digital output when your device is connected via USB, the app includes 16,384 bands of touch-adjustable equalization so you can create and save EQ levels to suit different kinds of music. You can also add songs to Favorites and enjoy easy navigation of your device’s music library. 

Free Access to HD Player Pack Upgrade for iOS and Android
When you connect your iOS/Android device to the DAC-HA300 via USB cable, you automatically receive free access to HD Player Pack for as long as you remain connected. Normally an optional in-app purchase, HD Player Pack allows you to load Hi-Res Audio files onto your device and output them to the DAC-HA300 at their native resolution, while a HD Equalizer and the ability to create and save playlists for Hi-Res music are also enabled.

Class-leading Hi-Fi Amplification

Onkyo has more than 65 years’ experience crafting some of the best-sounding audio equipment in the world. That heritage is clear the moment you plug your headphones into the DAC-HA300. Where similar products use an inexpensive integrated circuit to amplify incoming signals, Onkyo instead handpicked the legendary MUSES8920 operational amplifier—a discrete component that uses high-quality materials and an optimized circuit layout to achieve remarkably clear, open, and realistic audio reproduction. The op-amp is married to a fully discrete push-pull output stage that gives the DAC-HA300 its exceptionally high driving power and low-distortion performance.

Premium Digital-to-Analog Conversion Technology

The DAC-HA300 features the TI Burr-Brown PCM1795 Stereo DAC commonly used in high-end audio equipment thanks to its low out-of-band noise performance and high resistance to jitter. Connect the DAC-HA300 to your external media player via USB or the switching optical/coaxial line input and the PCM1795 takes over D/A conversion, resulting in drastically improved audio performance. When connected to your PC or Android device, D/A conversion is performed asynchronously, meaning that the DAC-HA300 takes over clocking (signal timing), opening out the soundstage, improving transient response, and uncovering layers of previously hidden detail.

Selectable Gain for High-Impedance Headphones 
This high-quality headphone amplifier has power to drive any of the headphones in your collection. A two-stage gain switch allows you to select the appropriate amount of gain needed for low-impedance IEMs when you’re out and about, while boosting power for full-sized headphones when you’re at home or the office. Thanks to its high output, you’ll never be wishing for that bit of extra volume again.

Combined Digital and Analog Line Input

A single line input handles both coaxial/optical digital and analog signals from connected devices. Digital-to-analog conversion is also performed by the DAC-HA300 when connected to media players with a digital output at a maximum 192 kHz/24-bit resolution. This is handy for connecting digital components like CD streamers or for analog tape decks and compatible record players.

USB-Charging Lithium-ion Battery

The lithium-ion battery inside the DAC-HA300 returns up to 7 hours of playtime with iOS devices, making it one of the longer-lasting DAC/amps on the market. Connect to a PC via USB to recharge or use the supplied DC to USB cable for rapid battery replenishment.

Tough, Compact, and Stylish
Although it’s very small and lightweight, the DAC-HA300 boasts a tough and strong aluminum body. It’s easy to use when you’re on the move with a large knurled volume control knob, positive-action buttons and switches, and easy-to-read OLED screen. A fully self-contained portable Hi-Res Audio player, you can slip in your back pocket and take premium sound quality wherever you go, or connect it to your phone via USB and stow it into your satchel while you listen and use other applications.
