SBooster makes an adapter for Lumin that allows you to hook up a LPS. I upgraded the power supply on my Node 2i and it made lots of improvement. I used a PD Creative board. They also make Power Supply improvement for U1 mini.. Might affect warranty. Just food for thought. .
Best streamers WITHOUT a DAC
A year or so I jumped into the streaming world with the Bluesound ecosystem. Overall I'm very happy with it. Still, I think I can do better than the Node 2i on my "reference" system, basically a vintage high end setup (Sonic Frontiers SFD-2 Mk III, Krell KBL, ML no. 332, factory rebuilt Maggie MG 3a's). I've compared the 2i's internal DAC with the SFD-2s and it isn't even close. Not surprising, as the SFD-2 Mk III is certainly one of the best DACs ever made despite its age. So, can anybody suggest a suitable DACless streamer? Comments appreciated, thanks.
