Lumin U1 Digital Transport/Streamer

 

 

 

“OK, I’m firmly in the “bits-is-bits” camp when it comes to talking sound quality from what is essentially a purely digital signal. And I would have said that the Lumin U1 would have the same sound as a NAD or a Pioneer or any other music server “client.” After all, the only thing that comes out of the device is “bits!” Well, I was wrong. Compared to the digital output of the Oppo or the Logitech device, the U1 was, well, just better! First of all, the top octaves were cleaner and more delineated. … the Lumin seemed to delineate the transients better than the other two and the pianos seem to have more “space” around them.”

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.
