THE AUDIOPHILE STREAMING TRANSPORT

A LUMIN for DAC owners; LUMIN U1 focusses on pure digital.

WHY LUMIN U1

After years of requests from existing high-end DAC owners, the LUMIN team have taken the finest components from the flagship S1 model and developed them specifically for digital processing and output.

Using a new dedicated LUMIN U1 processor adds upsampling and downsampling for every supported format – all the way from 44.1kHz to DSD128 – providing maximum DAC compatibility and optimization.

Transport-only unit based on the award-winning LUMIN S1
