Why the X1

The X1 isn’t “just another streamer.” It’s designed like a true reference front end:

• Dual ESS ES9038Pro DAC chips in a fully balanced layout

• Lundahl LL7401 output transformers on the analog outputs (XLR/RCA)

• Femto clock system with FPGA distribution for timing precision

• External solid billet CNC dual-toroidal PSU with separate digital/analog circuitry + low-noise linear regulation

• Optical network (SFP) plus RJ45 gigabit Ethernet (great for systems that benefit from fiber isolation)

Biggest Advantage: LEEDH Processing (why this can sound better)

One of the X1’s real “system upgrade” features is Leedh Processing lossless digital volume control.

In plain English, it’s a volume algorithm designed to eliminate rounding errors and adjust level without changing the signal’s shape—aimed at avoiding the typical resolution loss of standard digital volume controls and improve the sound coming out of output. It can remove the need for a separate preamp in more systems, letting you run X1 direct to a power amp (cleaner chain, fewer boxes/cables, often lower noise). LUMIN even documents direct-to-amp scenarios where Leedh is the default choice

Music Sources + Control

The X1 supports the major ecosystems buyers want today:

• Roon Ready

• Qobuz Connect

• TIDAL Connect (including TIDAL MAX icons and MQA support listed in app features)

• Spotify Connect

• AirPlay compatible

• TuneIn Internet Radio (native app support)

• Also supports UPnP/OpenHome and “Plays with Audirvāna” / JPLAY Certified as listed by LUMIN.

LUMIN App is actually excellent. Beyond basic playback, the app gives deep system control—display/customization preferences, upsampling options, polarity inversion, DSD↔PCM conversion options, and more. By using this Lumin app, the LUMIN X1 Flagship Streamer/DAC + External PSU  possesses  the continuous ability to upgrade features and soumd through firmware updates.
