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.
