New streamer? N150 vs U2

So many people have asked this question and I’ve read all the threads. Has anyone actually directly compared the Aurender N150 to the Lumin U2 (or U1)? 
 

‘’I’m having a difficult time with an upgrade because I modified my BlueSound Node 2i, added a linear power supply and a new digital coaxial cable (Nordost Silver Shadow).  The results have been outstanding.  So why upgrade? Well, that is the big question.  Can a new streamer add that much more?

 I would like full MQA if possible and upscaling to DSD.  My DAC does do MQA so I’m limited to the first unfold from the Node 2i.

‘Advice?
