Roon Instructions:
In Roon, tap the speaker icon in the bottom right corner, tap "DSP". tap "Headroom Management", and set the value to -5 dB, this lowers the level before oversampling to avoid clipping during the oversampling process. In the same field, set "Show Clipping Indicator" to "on". This will tell you if you have an clipping during playback (if you do, you can lower the headroom management a couple more dB, but usually -5 dB is enough). Tap, "Sample Rate Conversion", and set sample rate conversion to "DSD". Set "DSD Sample Rate" to 256, Set "Sample Rate Conversion Filter" to "Precise, Linear Phase" (I prefer this setting, but you can try others of course). Set "Sigma Delta Modulator" to "7th order CLANS", leave "SDM Gain Adjustment" at "0", set "Parallelize Sigma-Delta Modulator" to "Yes", set "Enable Native DSD Processing" to "Yes". The DSD to PCM settings are irrelevant.
Before you exit, double check on the left that "Headroom Management", and "Sample Rate Conversion" are enabled.
Just thought I would share with this group.
P.S. Looking forward to my Gaia- should ship within the next week or two!
