New DAC not streaming hi res files

I just obtained the Chord Qutest DAC in the hope of streaming hi res files. In short, it’s not doing it.
The indicator that changes colors with each different sampling rate remains fixed at the lowest color setting when streaming hi res files from Qobuz.  I have an Arcam  streamer  connected to the DAC  with a coax cable attached to a BNC adapter, as the Chord doesn’t have a coax accepter. And The Arcam doesn’t accept optical cables.
Could these connections be at fault?  I don’t know how to circumvent the problem
