Lumin T3X Network Music Player

An upgrade from the T3 with toroidal power supply, fiber networking, and extra USB port

The LUMIN T3X DAC/Streamer delivers exceptional sound quality and state-of-the-art features in a compact, elegant design. Positioned as the upgraded model of the award-winning LUMIN T3, it introduces advanced innovations and premium components, setting a new standard for digital music streaming. T3X takes what the T3 offered and adds the toroidal linear power supply from the U2, the fiber networking of Lumin flagship players, and an extra USB port for even more flexibility. Truly next-level performance for your system.

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 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.

LEEDH Volume Control

Lumin’s LEEDH lossless digital volume processing was a major upgrade delivered free over-the-air to all Lumin products. LEEDH is a significant improvement over a traditional digital volume control design. Some Upscale customers and employees have even removed preamps from their systems, finding LEEDH to be better-sounding than the analog volume knobs.

LEEDH processing is roughly analogous to a resistor ladder volume in that there is a set of specific steps of loudness from silent to 100%. These steps are calculated to be where the digital attenuation results in an exact answer. As a simplified example, it might choose to divide 15 by 3 and get 5.0, rather than 14 by 3 and get 4.66666666667, which is truncated to 4.66 by "throwing away bits."

LEEDH processing preserves detail, dynamics, and transparency even at low volume levels—without the resolution loss of traditional digital volume controls. Found in ultra-high-end products like the $72,000 Soulution 760 DAC, Lumin brings this advanced technology from their flagship X2 all the way down to the D3.
