I had the same problem where the streamer without DAC that I bought cannot match the SQ of my SACD player. Streamer USB output was connected to USB DAC input of SACD player. I compared playing ripped files inside streamer SSD vs SACD player playing discs. My own reasoning - CD/SACD player has very short signal path internally, and a good player has very good power supply.
Since then, I have learnt a lot about computer audio that my DIY streamer SQ can match the SACD player SQ. But this is a different topic, best discussed in Computer Audiophile forum, not here.
FYI Lumin D2 uses internal switching mode power supply.
