The Lumin U2 Network Transport pairs a dedicated direct-coupled USB audio output with advanced optical network connectivity to stream pure digital audio straight to external DAC's Network Players and high-performance standalone converters. By eliminating internal digital-to-analogue conversion stages, the Lumin U2 dedicates its processing power exclusively to source playback, feeding your downstream audio gear with pristine, jitter-free bitstreams.Ultra-Clean Power Architecture:An internal linear power supply featuring an ultra-low-noise toroidal transformer and high-grade linear regulators generates clean, quiet direct current for the processing electronics. Enclosed within a solid CNC-machined aluminum chassis, the sensitive digital signal paths remain shielded from external airborne radio interference and mechanical vibrations, allowing subtle details and instrumental textures in every track to emerge naturally.Fibre Optical Isolation and Dual-Network Connectivity:Dual network interfaces, including an industry-standard optical SFP port alongside a standard Gigabit Ethernet port, provide total galvanic isolation from domestic network noise. Routing your home network traffic through optical fibre isolates electrical hum and unwanted line noise before it ever reaches your audio pipeline, ensuring a whisper-quiet background during intimate listening sessions.Extensive Format Support and Streaming Flexibility:Engineered to handle native DSD512 and PCM streams up to 768kHz via its dedicated USB audio output, the Lumin U2 plays high-resolution files with absolute accuracy. Native compatibility with Roon Ready systems, UPnP, TIDAL Connect, Qobuz, and Spotify gives you seamless control across your preferred music platforms through the responsive Lumin control application or favourite streaming apps.Lossless Volume Management:Integrated Leedh Processing digital volume control recalculates signal amplitude without the digital truncation and rounding errors common to standard digital attenuators. This transparent algorithm allows you to connect the transport directly to active loudspeakers or power amplifiers via your external DAC without compromising dynamic range or sonic fidelity.Authorized Dealer:We are an authorized dealer for Lumin audio equipment. Purchasing from a trusted brand partner gives you total peace of mind, providing full manufacturer's warranty coverage alongside dedicated technical guidance whenever you choose to expand your high-fidelity music collection.Key Features and Benefits: Dedicated USB Audio Output: Provides a low-noise, direct-coupled digital output delivering native DSD512 and 768kHz PCM directly to your DAC.
