I just got my Direct Stream DAC and connected it to my Aurender S10 Music Player using a digital RCA-cable for S/PDIF (Nordost Valhalla). It all works and sounds great for all my music files except those in 192kHz. When trying to play such a file, the front display changes back and forth between 96 and 192 kHz, bot no signal comes from the analog outputs. Does anyone know if there are any known issues using the Aurender with the DSD? For the record, I have not tried any of the other digital interfaces like AES/EBU or USB.
