How are you getting Quobuz into the DAC? From a PC, or from the Arcam? Do you have High Rez files stored on a Hard Drive somewhere? If the answer is yes, Is the DAC reading those files?
if Quobuz is coming from a PC, check the output settings on the PC, as it may be downsampling High Rez content before it sends it to the DAC. Are you sure that the Arcam is speed to handle High Rez files?
