The upgraded audio section utilizes two ESS ES9069Q DACs and pairs them with dual SGM8262 amplifiers for a fully balanced headphone output. Together, they offer up to 626mW @ 32Ω output power, running directly from the internal battery, without any need for external power and extra cables. With such powerful output, UP6 belongs among the most powerful compact Bluetooth DACs and easily matches top-tier USB dongle DACs. Its Bluetooth section has been modernized with the Qualcomm QCC5125 module, bringing support of LDAC, aptX HD, aptX Adaptive & AAC for smooth and top-quality wireless streaming. And when the occasion allows, the UP6 can be used as a USB DAC with computers or smartphones, taking full advantage of lossless Hi-Res playback thanks to the XMOS XU316 USB input.
