  • Geek Out 2Pro is a high performance portable USB digital-to-analog converter (DAC) and pure Class A headphone amplifier that builds upon the success of the Geek Out V2+.

    Geek Out 2Pro is the master of adaptability. Leveraging its own dedicated 3200mAH Lithium-Ion battery power supply, we’ve designed it to be compatible with iOS (with Apple Camera Kit), Android Lollipop 5.0 & USB 2.0 audio class compatible devices without draining your source device’s power.

    Geek Out 2Pro has been designed with multiple selectable analog gain stages to accommodate the growing headphone collections of many audiophiles in one portable device.

    Geek Out 2Pro accepts digital audio signals through USB and outputs audio signals via 1/8”/3.5mm single-ended and balanced headphone jacks.

    When used in conjunction with the appropriate playback software, Geek Out 2Pro will decode almost any music file format and resolution available, up to and including Direct-Stream Digital (DSD).

    Versatile at its core

    GO2Pro is the most transparent DAC you can find, supporting your lowest format Mp3 to the highest PCM up to 32/384 kHz and DSD for up to 128 times the sample rate of a CD! If you have a Hi-res player on your phone, you need to have the hardware that can compliment it.

    The most powerful Amplifier

    Our GO2Pro is twenty-five times more powerful than a laptop or phone’s output jack, GO2Pro can drive any set of headphones using your Laptop or Android phone with a three step gain stage for any In-ear buds, On-ear Headphones, or those big cans you wish your cell phone could drive.
