Hi. @txp1,
I have the newest Node with the Teddy Pardo PSU, with an Audience PC, a DH Labs, Mirage USB, going to a Denafrips Pontus ll DAC. Put it all together and I have @$2800 in my streamer/DAC. Will a N150 or a U2 sound different, would be my question.
To me, better is in the ear of the beholder.
All the best.
