Lumin U2 Streamer

A high-end streamer withdigital volume control, Roon Ready, built-in network switchfor NAS, and new internal linear power supply.

After the success of Lumin’s single chassis, high-performance products such as the T3 and P1, these Hong Kongbased digital masters bring their low-noise, highly musical designs to a single chassis high-end streamer.

The all-new for 2023 U2 sits between the U2 MINI and the U1, andhas the same high-end chassis construction as the top-flight products. The PSU may be internal but it is a well-shielded linear power supply based on a high-quality toroidal transformer.

The U2 uses Lumin’s latest processor, bringing tremendous upsampling flexibility.An optical fiber network jack providescomplete isolation from network digital noise. There are three USB ports including adedicated low-noise USB audio output. The other two can be used for thumb drives, hard drives, and other music storage options.

A built-in network switch allows you to connect the U2 to your router using, say, the optical network, and connect to your NAS using the RJ45 connector.

Lumin’s celebrated LEEDH digital volume processing allows you to eliminate a preamp and connect your DAC directly to a power amp. LEEDH processing is totally lossless and both Upscale crew and customers reportthat it sounds fantastic.

The Upscale View

Lumin is THE brand for hi-fi enthusiasts who don’t need touchscreens, knobs, and a host of extra features. With its background in broadcast engineering, Lumin epitomizes providing the lowest noise and most stable, high-bandwidth circuits. On a Lumin, everything extraneous can be turned off: unused digital outputs, unused processing streams such as Roon and Lumin streaming, the display, and even the RJ45 LEDs. The result of this tight focus is a light, lithe, airy sound with a huge, natural soundstage, and no artificial warmth or bloom.

Sure, the Lumin app takes a little getting used to, but once you’re comfortable, it’s fast, stable and most of all, sounds the best.
