LUMIN U2X: The Ultimate Digital Transport for Discerning Audiophiles

frank Sources

Network streaming specialist LUMIN has unveiled their latest flagship digital transport, the U2X, representing the pinnacle of streaming technology for dedicated DAC owners. This meticulously engineered two-piece design features a separate external power supply, revolutionary isolated circuit architecture, dedicated Audio USB output, internal 10MHz clocking, built-in network switch with both RJ45 and fiber optic connectivity, the renowned Leedh Processing lossless volume control, and precision-machined aluminum construction throughout.

LUMIN U2X

The LUMIN U2X stands as the ultimate network streaming transport, purposefully designed without integrated DAC circuitry to allow audiophiles the freedom to pair it with their preferred high-end digital-to-analog converter. The U2X excels exclusively at receiving and processing network-based digital music files, employing cutting-edge computational systems capable of upsampling and downsampling to DSD256. It handles every conceivable audio format, including native DSD512 and PCM768, while its enhanced clocking capabilities can both output and receive 10MHz clock signals to synchronize entire digital audio systems. Through sophisticated software-hardware integration and partnerships with leading streaming services, the U2X provides access to an unprecedented array of music sources, including the latest addition of KKBOX.

Uncompromising Power Supply Design

The U2X's power supply architecture represents a masterclass in electrical isolation, housed in a separate chassis to eliminate any potential transformer-induced vibration and interference. The external power supply features dual toroidal transformers, dedicated to digital and analog circuits respectively, coupled with ultra-low-noise linear regulation and the finest available components. Both the power supply and main transport chassis are crafted from single-billet CNC-machined aluminum, delivering maximum isolation and structural integrity.

Advanced Digital Connectivity

The U2X's USB implementation showcases LUMIN's commitment to signal purity, featuring three USB ports with one designated as the primary Audio USB output. This dedicated port utilizes newly developed isolated circuitry, completely separated from other digital pathways to achieve unprecedented low-noise performance. The remaining two USB ports accommodate external storage drives and additional peripherals. The integrated network switch functionality accepts both Ethernet RJ45 and fiber optic connections, providing the cleanest possible network input pathway.

Comprehensive Streaming Ecosystem

Beyond its exceptional hardware foundation, LUMIN maintains an expansive software platform with broad compatibility across major streaming services. The U2X seamlessly integrates with TIDAL, TIDAL Connect, Qobuz, Qobuz Connect, KKBOX, Spotify, Audirvana, QQ Music, and PLEX, while supporting Roon Ready, MQA, AirPlay, TUNE IN, and multi-room applications.
