I need a new streamer.

The Lumin U2 Mini is an amazing device! You can upgrade its power supply & power cord by a decent LPS and the sound will improve even more.
The head of firmware of LUMIN is very active on various online forums too. Concerning upsampling he suggests for example when using Roon or HQPlayer to do that on that device - so there is less stress on the streamer which will provide a better audio quality.
When doing Upsampling it’s important to use what suits your DAC - so that you already send in the format the DAC can use right away without any further internal processing.

Thanks Markush!  This is a 7 month old trade in and the “SBooster” power upgrade has already been done.
 
I picked it up yesterday and even with an optical cord (my digital coax cord is on order) I found a big difference compared to direct streaming from my computer.  Once the cable comes I can start tweaking it a bit.  The interesting option is that it has an internal Leedh’s volume control which eliminates rounding errors in the information while adjusting volume. Those that use it really like it.   And I did find the head of firmware on Loon Community which has helped.
