The problem seems to be when the Explorer2 is connected & selected as the Digital output through the SBT. Roon (or something) doesn't like that combination.
And this is not (music) file-dependent - I can play normal FLAC or MQA into the SBT with the Explorer2 connected, and a power light on, but with "Digital" (SPDIF) output selected.

@Joel : did you do something specific when you connected your Explorer2 ?
Did you (simply) update the firmware on the 4th February, plug-in to the SBT, select the Explorer2 as the output & you were good to go ?
Does it work with a direct headphone connection to the Explorer2, or only with line-out ? Does it work with nothing connected to the outputs at all ?

Ta !

EDIT : Just connected the Explorer2 to my PC & can immediately play MQA - through Roon - with all the lights showing as appropriate. Which means it's not the Explorer2. Well, not when connected to a PC anyway....

EDIT2 : Just tried the same procedure with a different SBT - same problem is reproduced. Frustrating, but consistent.

EDIT3 : Have also posted on the Roon forum in case anyone else has any ideas....
