WHY LUMIN U2

After the huge success of our sweetspot price/performance LUMIN T3, LUMIN U2 brings the same design philosophy to a transport for the first time.

Taking chassis construction methods, linear power supply design and dual-network from the multi-award-winning LUMIN P1, the all-new LUMIN U2 brings high-end digital right into the heart of the LUMIN range.

Transport-only unit featuring the finest LUMIN components

First LUMIN Transport to use new all-in-one chassis Latest processor provides greater resampling flexibility New integrated toroidal linear power supply Fibre Network provides complete isolation from network digital noise Increased capacity for future updates 3 USB ports including a NEW dedicated low-noise USB output Dual-Network interface with built-in Network Switch DSD512 and PCM768 playback 4 exceptionally low-phase-noise crystal clock oscillators New surface finish taken from the high-end P1 Leedh Processing lossless volume control

All-new processing system

Completely new next-generation hardware and software provide a new foundation for LUMIN Increased processing power and storage capacity provide greater resampling flexibility, audio processing performance and future-proofing. Up/down sampling up to DSD256

Internal ultra-low-noise linear power supply

First LUMIN Transport with a built in linear power supply Ultra-low-noise rectifier and linear regulator Extra large toroidal transformer

Dedicated USB port for Audio Output

First LUMIN to feature 3 USB ports New dedicated “Direct-Coupled” USB digital audio output port Leaves two ports free for music storage and accessories

CNC chassis construction

First LUMIN Transport to use new all-in-one chassis The thick CNC panelled aluminium construction offers upgraded structural rigidity and sheilding compared to the U2-Mini Precision CNC milling techniques from our flagship products provide the high-end LUMIN family aesthetic

Draws the very best aspects from throughout the LUMIN range

New processing hardware and software first introduced with the U2-Mini and T3

The best features used from our flagship players such as Fibre Networking, Linear Power Supply and Dual-stage voltage regulators

New for a LUMIN Transport - U2 uses CNC panel construction finished in a new silky surfacing process taken from our high-end P1 that is less susceptible to finger marks and easier to clean.
