Dang it. This product has been discontinued. It has reached its end of life. It has ceased to be. It is no more. For a great alternative, check out the XD-05 DAC/Amp. Level up The xDuoo XD-05 Basic is a DAC/Amp that’s powerful enough for your desktop yet portable enough for your pocket. Featuring an audiophile-grade digital-to-analog (DAC) chip, input connections for all the major consoles, and massive output power, it’s a power up for any gaming rig. Pro gamer-grade sound With an ES9018K2M digital-to-analog converter (DAC), the XD-05 Basic supports playback of sample rates up to PCM 32bit/384kHz and DSD256 (basically the audio equivalent of 8K video). Bump it A bass switch on the front plate gives you that extra oomph when you need it: when you’re fighting for your life in a AAA game or when the beat of your favorite track drops. A force to be reckoned with Boasting 500mW of output power, the XD-05 Basic can drive nearly any phone you throw at it, whether they be IEMs or power-hungry planar magnetics. Peacekeeping the console war There may be a console war raging, but you wouldn’t know it from looking at the XD-05 Basic’s back plate. With support for USB Type-C, optical, and line-in inputs, this DAC/Amp plays nice with Switch, PS4, X-Box, and PC. Excursion-ready Are all gamers vitamin D-deficient homebodies? Sure, but they don’t have to be. With over nine hours of battery life, the XD-05 Basic can free any gamer from the nomadic restrictions of stationary equipment and help them, you know, see the sun every once in a while. (Pairs really nicely with the Nintendo Switch!)
