Equipped with a number of connections for pairing with all your favorite devices, the xDuoo XD-05 portable DAC and headphone amp is incredibly versatile for its size. Use the auxiliary input to plug in your digital audio player, the auxiliary output to send the signal out to speakers, the USB input to connect your computer, and the micro-USB port to charge up when you need to. The XD-05 supports PCM signals up to 32 bit/384 kHz and native DSD decoding up to DSD256, with seven different DAC filter settings so you never get bored.
Note: At checkout, you’ll have your choice of colors between black and silver.
Made from anodized aluminum alloy with a sandblasted surface, the enclosure measures just 5.5 inches long and 3 inches wide. On the front panel, you’ll find an OLED screen that displays product information in real time, along with switches for bass boost, gain, and input selection. And good news for modders: Should you ever want an upgrade, the opamps inside the XD-05 are easy to swap out and replace with your own.
