The Skinny

  • Transport-only unit based on the award-winning LUMIN S1
  • 5 types of digital audio output including new USB
  • Includes DSD512 22.5Mhz 1-bit playback
  • PCM 44.1–768kHz 16–32-bit
  • 4 exceptionally low-phase-noise crystal clock oscillators
  • External dual-toroidal power supply
  • Resampling to every supported format up to DSD128 and PCM384kHz
  • Supports DoP (DSD over PCM) for Optical, Coaxial RCA, Coaxial BNC & AES/EUB SPDIF

In other words, the Lumin U1 is the Lumin S1 minus the DAC. Using a new dedicated LUMIN U1 processor adds upsampling and downsampling for every supported format – all the way from 44.1kHz to DSD256 and DXD – providing maximum DAC compatibility and optimization.

As well as supporting DSD output over SPDIF (via DoP), LUMIN U1 also adds DSD256 digital output via 2 new USB ports.

    The Perfect Streamer

    Posted by Unknown on 7th Sep 2019

    This is an expensive product, but takes audio streaming to a different level. The accurate placing of instruments and voices in space impressed immediately, but that wouldn't be enough; it is their true timbre that keeps me listening. Rattle's Beethoven 3 had me transfixed, while Van Morrison's His Band and Street Choir, not a great recording, emerged new-minted. Roon delivers as faultlessly as the excellent proprietary app, an important consideration. I was advised to use AES after a few days' burn-in, but with my Luxman DAC, the USB sounds warmer, which I like, and gives more upsampling options. I'm very happy, and if I were wealthy would go for an X1 in a heartbeat!
