Hi @Paul ----- Thanks for the feedback and sharing your observations with us, both are appreciated!
Moving forward, to help aide in my evaluation of this behavior you are reporting to us, may I kindly ask you to provide/verify the following information for me:
-
Can you please expand on description of your current setup as seen here.
-
Please provide the following screen shots:
-
The signal path leaving Roon when you notice the hissing/interference noise.
-
The device settings being used for the MicroRendu + Vega DAC zone. This information can be found by going into the audio tab, clicking the gear next to the desired zone, and selecting “device setup”. Please be sure to provide screenshots from all three tabs: “General”, “Playback”, and “Zone Grouping”.
-
Screenshots of your DSP engine settings.
- If you were to not use the DSP feature in Roon and play some DSD 128 content, what is the experience like? Do you still receive the same results?
