Lumin X1

Audiophile Music Streamer/DAC/Preamp With Lossless Volume Control





LEEDH Processing Lossless Volume Control

LUMIN users now have the option to use (at no additional cost) Leedh Processing Lossless Volume Control.

What Is LEEDH?

LEEDH Processing is an innovative new digital volume adjustment algorithm that eliminates rounding errors. It Modifies the digital signal amplitude exactly, without any changes to its shape and free from any kind of information loss, and uses more efficient whole number volume values to maintain audio information integrity during subsequent DAC conversion. If you are using a Lumin streamer DAC as your source for music, you no longer need a preamplifier, extra interconnects and cabling (not to mention distortion and noise). All you need is the streamer/DAC like the X1 or T2, the Lumin Amp, or your own amplifier. No more preamp, for real. Less is indeed more.


“The most impressive feature of the combo hid inside the X1 streamer with the new Leedh Processor obviating a preamplifier no matter how good.”

“Leedh Processing has significantly boosted the performance of Lumin’s network players. There is more clarity, more detail, more timbral accuracy, higher dynamics, less distortion. It’s a bit complicated to explain what happens exactly but as soon as you trigger Leedh, you understand to what extent all usual preamplifiers add their own colorations.”


How Does This Benefit Your Audio System?

If you are running a streaming only system. The Lumin X1 with LEEDH processing allows you to dispense with your preamp altogether, creating a shorter signal path, with fewer cables, tubes, etc. and ultimately a purer more resolving signal. You run the outputs of the X1 directly to your amplifier (s). The LEEDH volume control transparently controls the volume level to your amp(s). This is not like any other digital volume control. Gone are the compromises of lossy volume controls. On top of that, the purity, dynamics and resolution are better than with any preamp.


Why Lumin X1

If you desire the most fulfilling, engaging listening experience look no further. The Lumin X1 is the result of the passionate pursuit of excellence in digital audio playback. Underneath the billet aluminum chassis of the X1 lies a dual-mono architecture with dual-stage linear regulators and a femto master clock under FPGA control. The X1 power supply in matching solid billet case has twin power toroidal transformers and separates digital and analog power feeds.

The secret to the Lumin X1’s relaxed, warm, lit from within sound might be the Lundahl output transformers. Sixmoon’s own Srajan Ebaen says “The X1 could undoubtedly do mellow, elegiac, elegant and gorgeous; more no-feedback triode than feedback pentode.”

Re-engineered throughout

LUMIN X1 makes improvements in every possible location:

  • A new processor delivers native DSD512 & PCM768 playback
  • The dual mono design throughout maximises channel separation
  • Dual ES9038Pro SABRE DACs featuring 140dB dynamic range
  • A femto clock system with precision FPGA distribution reduces jitter distortion
  • A new output buffer design
  • Dual Mono dual stage linear regulator
  • Optical Network provides complete isolation from network digital noise
  • USB Digital Audio Output supports Native DSD512

The X1’s Entirely new Power Supply

  • New solid billet CNC casing design
  • Separate digital & analogue circuitry
  • Low-noise linear regulator
  • New 9-pin output connector
  • Available as an upgrade for existing S1 / A1 / T1 customers


Pairing the Lumin X1 With The Lumin Amp

The Lumin amp is the perfect partner to the X1. They were quite literally made for each other, and with LEEDH Lossless Volume one can eliminate a preamp if the streamer is your sole source of music. Less noise distortion, and greater resolution await.
