  • Onkyo is introducing their new DAC-HA300 D/A Converter/Headphone Amplifier/SD Player to bring high-fidelity headphone amplification and D/A decoding for Hi-Res Audio to your everyday portable audio setup.
    With a slot accommodating up to 128 GB of music stored on microSD card, an OLED screen, and easy playback controls, the DAC-HA300 also serves as a self-contained media player and headphone amplifier, while a Micro USB Type-B input enables asynchronous D/A conversion of Hi-Res Audio from PC without need to install drivers.

    The device also features a switching optical/coaxial/analogue input capable of accepting digital signals from connected devices up to a maximum 192/24 resolution.

    The DA-HA300 dovetails with Onkyo’s HF Player application for iOS and Android devices. When the DAC-HA300 is connected to the mobile handset via USB (standard Lightning cable for iOS devices, OTG (On-the-Go) cable for Android), a free app upgrade to HD Player Pack enables output of Hi-Res PCM and 5.6 MHz DSD files at native resolution to the DAC-HA300 for decoding and playback—a first for the portable audio industry.

    The application also imports and presents other audio formats stored on mobile in a clear user interface, and includes a 16,384-band FIR equalizer that allows users to create and save their preferred EQ settings for specific artists, genres, or albums.

    Rather than using a low-cost integrated circuit amplifier, the unit is based around the MUSES8920 op-amp, a discrete, high-quality audio component with an optimised circuit layout to ensure signals are amplified with minimal distortion— a claimed 0.004% THD+N at 32 Ohms (100 mW + 100 mW, JEITA). There’s also a fully discrete push-pull output stage and a selectable gain adjustment function so it should drive any headphones, from low impedance IEMs to full-sized 600-Ohm open-backed cans.

    Likewise, the 192 kHz/32-bit TI Burr-Brown PCM1795 Digital-to-Analogue Converter was for its exceptionally low out-of-band noise performance and excellent resistance to jitter.

    The DAC-HA300 includes a long-life internal lithium-ion battery that returns approximately seven hours of playback when connected to an iPhone via USB Type-A input, and can be recharged via USB and PC or more rapidly with the supplied 5 V DC cable and plug.

    The DAC-HA300 is available in any colour, so long as it’s black, and it’s due toward the end of April with a price of £499.
