LUMIN U1

Purchased just a little over 1 year. Rated 9 because it is over a year old, but mint in all other ways. A great streamer! I am only replacing because I purchased a DCS DAC which has a streamer. Pleas check my feedback.

An S1 without the DAC!

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 and DXD – providing maximum DAC compatibility and optimization.

As well as supporting DSD output over SPDIF (via DoP), LUMIN U1 also adds DSD128 digital output via 2 new USB ports.
