Dear users of the Media Center, please advise, if you know how to properly configure the playback of media files (Flac of different quality and DSD) from my computer Mac through a network connection to Teac NT505 DAC. When connecting via USB all works correctly and I can see on the screen of the DAC the correct characteristic of the playing file on the input and output of the DAC. For example, PCM 44.1, 16 Bit; PCM 96 kHz, 24 Bit; PCM 192 kHz, 24 Bit; DSD 64; DSD 128 and so on in the input are displayed the same way on the output, if I do not use upsampling. If I connect the DAC to the computer via the Ethernet port (LAN), then the same files are perceived on the input as MP3. For example, the file PCM 44.1 kHz, 16 Bit is seen at the input as MP3 44.1 kHz and played as PCM 44.1 kHz if I do not use upsampling. Files with a bitrate higher than that (PCM 96 or DSD) are seen on the input as a 48 kHz MP3. I do not understand what the problem is and how to properly configure my MC25 to properly transfer files over the network and would appreciate your advice.
