I cannot play DSD files

[Aldo]

I have just tried again. I use mconnectHD on an iPad to browse the NAS with the music files via MinimServer[myname]. The server is connected via Ethernet to a router, which in turn is connected to the DAC via an Ethernet cable with UPnP. I first tried both 64 and 128 DSD files, both playable by the DAC over DoP according to specs. Marked distortion with both, worse with 128. After that I also tested a variety of PCM files from the NAS: all distorted and also distortion in the PCM files I played from Qobuz.

I then switched the DAC off, and back on: at this point PCM files from Qobuz AND from the NAS sound normal again.

It’s as if playing DSD with the NAS “alters” the DAC, and the alteration disappears once it’s turned off and on again.
