Lumin U2X Streamer Transport with ext Power Supply (without DAC)

LUMIN U2X

The new benchmark for high-end streaming transports

The U2X is LUMIN's new flagship streamer—uncompromisingly engineered for digital perfection. No DAC, no bells and whistles. Just pure, clean digital output of the highest quality.

With a chassis CNC-machined from a solid block of aluminum, the U2X feels as premium as it sounds. It also features an external linear power supply with two toroidal transformers in a "tank" design, inspired by the legendary LUMIN X1.

Solid, precise, uncompromising

What looks like a design statement is actually a masterpiece of engineering: Thick aluminum walls for maximum stability and shielding. Mechanical and electrical interference? Not a chance.

Fully digital. Fully LUMIN.

The U2X has everything you would expect from a modern high-end van – and a little more:

Native playback up to DSD512 & PCM768

New clock circuit with 10 MHz clock in & two clock outs – perfect for multi-device sync via master clock

Dedicated, isolated USB audio output – plus two additional USB ports for music and accessories

Fiber optic network connection for maximum signal separation

Dual Ethernet with internal switch – a LUMIN innovation for trouble-free streaming

Plenty of connections

• USB audio out (isolated)
• Optical (Toslink)
• Coaxial RCA & BNC
• AES/EBU (XLR)
• 10M Clock In / 2x Clock Out
• Fiber Network (SFP)
• Dual LAN ports
• 2x USB for storage devices
• Isolated grounding

Faster, smarter, future-proof

Inside, the latest and fastest Lumin processor is at work – for the first time in the flagship transport. This means more power for upsampling, downsampling (up to DSD256), improved processing, and fast updates to keep you at the forefront of tomorrow.
