About the U1 Mini

The LUMIN U1 Mini is a DAC-less digital music transport designed to deliver high-resolution audio streaming and playback. It supports DSD playback up to DSD256 (11.2MHz, 1-bit) and PCM playback up to 384kHz at 16–32-bit stereo. The device features a quad native clock system for precision timing and a low noise shielded switching power supply. It offers multiple digital audio outputs including USB, AES/EBU, coaxial BNC and RCA, and optical TOSLINK, supporting DoP (DSD over PCM) for various outputs. The U1 Mini can upsample and downsample audio from 44.1kHz to DSD128 and PCM 384kHz, and supports MQA decoding for high-resolution streaming from services like TIDAL and Qobuz. It is Roon Ready and includes an innovative digital volume control algorithm called Leedh Processing, which allows volume adjustment in the digital domain without loss of audio information, while also allowing users to switch to analogue volume control if preferred. The unit is housed in a compact enclosure made of raw brushed or black anodised aluminium, measuring approximately 300x244x60mm and weighing about 3kg. It includes five digital outputs and supports USB inputs for portable storage devices. The internal power supply is shielded and auto-ranging (100–240V AC). The U1 Mini is praised for combining the power and features of the larger LUMIN U1 in a smaller, more affordable package, making it a versatile and high-quality transport for audiophiles.
