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 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.
