{"type":"firestarter.listing","listing":{"id":"lst_i-ulaf2f","product_name":"xDuoo Link 3 DAC Headphone Amp","category":"Headphone DAC/Amp","description":"xDuoo Link3 DAC Amp with Micro SD Expansion\nThe xDuoo Link3 is a portable USB DAC and headphone amplifier built for phones, tablets, handheld consoles, and computers that need better sound and stronger drive than a standard headphone jack or adapter can provide. It combines dual ES9039Q2M DAC chips, a 3.5mm output, a 4.4mm balanced headphone output, dual USB modes for music and gaming, a color display, detachable USB-C connectivity, and support for high-resolution PCM and DSD files in one compact body you can carry every day.\nDual outputs for more ways to listen\nLink3 gives you both a 3.5mm unbalanced output and a 4.4mm balanced headphone output, so it works with everyday headphones and more demanding balanced cables without forcing you into one path. That matters when you switch between simple portable headphones at work, in-ear monitors on the go, and harder-to-drive full-size headphones at home.\nPower that helps demanding headphones\nFor a device this size, Link3 offers useful output headroom. In normal mode it reaches up to 700mW at 32 ohms from the balanced output, and with external power connected it can reach up to 1000mW at 32 ohms. That extra power helps with control, volume margin, and low-end grip when you plug in headphones that need more than a phone can comfortably deliver.\nDual DAC architecture for cleaner conversion\nInside, Link3 uses two ES9039Q2M DAC chips along with an XMOS XU316 USB receiver. In practical terms, that means the digital signal coming from your phone, computer, or handheld gets converted with better precision before it reaches your headphones. xDuoo also lists up to 130dB SNR and THD+N as low as -112dB, which points to low background noise and solid control over distortion.\nHigh-resolution support that covers serious music libraries\nLink3 supports PCM up to 32-bit/768kHz and DSD up to DSD512, so it is ready for local hi-res files, lossless streaming, and larger digital music libraries without becoming the bottleneck.
