Maybe EverSolo DMP-A6? It measured well, and the UI is quite friendly.
Not a pure streamer though, but you can still use it as a digital transport since it has a digital output.

Could this be changed by future firmware updates? I’m trying to hook up a CD transport to this device and then send the signal to my DSP via digital output.
I googled the founder (Damian Demendecki) and found that he’s also interested in Grimm LS1be and Kii Three.
Looking forward to further information of the speakers!
