I have a rather novice question regarding the Roon settings for DSD files playing via SPDIF. I understand that SPDIF does not decode DSD files. I have a DDC connected to the DAC via SPDIF and I have some DSD files I would love to listen to.
I have set the DSD playback strategy as “convert to PCM”, Max sample rate (PCM) at max “up to 768kHz”, under DSP, Sample rate conversion is “enabled”. With this settings, there are no sound during DSD files playback but it functions well with normal WAV/FLAC/ALAC files.
Or have I misunderstood incorrectly? Any advice is greatly appreciated
Interesting. Could be that the highest rate that your DAC supports over S/PDIF is 96 kHz. Make sure that you are using a 75Ω digital cable and not a standard RCA cable. May be obvious, but I’ve seen some wild things out there.
That DAC is circa 2013 and is a bit of a beast, more than capable of playback of DSD up to DSD128. The problem is the DDC will allow you to set up any bit rate it is capable of regardless of what you have it connected to. In order to test it properly plug USB direct into your core and Roon should pick up its capabilities automatically. If you use the DDC then begin with maximum 192/24 and try DSD settings as DOP DSD64. That might work. Otherwise ditch the DDC for decent USB isolation and go that route.
I owned an SU 6, so I know it’s capabilities are tied to the DAC and specifically the input you choose. The Kitsune is using its i2S input, fully capable of mirroring USB performance. You are using coaxial SPDIF normally only specified up to 192/24 and maybe DOP at a push.
That is strange. You can try a different cable but otherwise it is difficult to say what the problem might be. I used my SU 6 with an AudioByte Black Dragon via the i2S so never used it into other inputs. I’m trying to remember what you could adjust using the dip switches but it may have just been the way the DDC handles DSD. I wish I could be of more help.
your inputs are greatly appreciated. Since both SU-6 & MH-DA002 are working well independently playing DSD files in other contexts mentioned earlier, it can be assumed that the possible weak link is the coaxial SPDIF cable. Will only know better after getting a new cable to test it out.
