iFi Audio GO link 2 | Portable DAC and Amp

iFi GO link 2 is a Hi-Res Plug-and-Play USB Dongle DAC, Perfect for Every Day Listening Supports Hi-Res PCM 384kHz + DSD256 ESS Hi-Fi DAC with jitter elimination Dynamic Range Enhancement technology 29% lighter and more compact body compared to original GO link Better Sound, Made Simple Smartphones and laptops aren't designed for great sound. Audio has long been an afterthought, built to be "good enough" for basic music playback. For music lovers, the step up to better sound has traditionally meant added cost and complexity. The GO link 2 breaks this barrier by bypassing the internals of your device and transforming it into a high-resolution music player. Dramatically Dynamic The GO link 2 brings music to life with exciting highs and deep lows, making every moment more intense and engaging. iFi has hacked the DAC chip to unlock Dynamic Range Enhancement, giving +6dB additional range between the loudest and quietest moments.  Distortion Defeated The GO link 2 includes enhancements unlocked within the DAC chipset to minimize total harmonic distortion, ensuring a cleaner, purer sound. By adjusting a correction factor inside the DAC chips, this rarely-used feature reduces the 2nd an 3rd harmonics, reducing distortion by up to 62% compared to the original GO link. Nexis, Unlocked The GO link 2 is the first model in the GO link range to include full compatibility with the iFi Nexis app. Firmware updates can be completed over-the-air in moments, without the need for download files or desktop computers. In addition, Nexis opens the door to new customization options. Balanced Performance  The GO link 2 is the latest device to incorporate iFi's in-house S-Balanced technology. This unique circuitry takes a different approach to how signal noise and crosstalk is handled. By applying balanced circuitry principles to the single-ended headphone output, S-Balanced technology cuts the crosstalk between headphone channels in half, to guarantee maximum performance with minimum interference.
