Thanks so much for posting such a detailed description of your setup and issue. Unfortunately, as the post wasn’t made in the Support category, our technical team was not notified. I’m tagging them here, @support, so they can take a look and help troubleshoot.
Everything sounds fine on the speakers on my Mac.
Screenshot is from my MacBookPro i7
As soon as I stream to the BlueSound devices I have these problems. Whether to a Puse Flex 2 i, or both, whether WiFi or LAN, or via the Node 2i to my floorstanding speakers. Whether Mac with audio interface, or MacBook Air without interface.
Volume Leveling is DSP although it’s settings are not found on the DSP page. It is found on the Zone settings page.
My Node 2i is Volume Leveling OFF.
Additionally, in the screen shot above it showed
That means that your Flex 2i is adding Crossover and EQ to the signal. I was suggesting that you go to the Flex settings and turn that off as well, because, that is also a difference between the Flex output and the Mac’s output.
I honestly have trouble understanding that. Or to understand Roon
Because, I can turn off DSP after all. I have too. And still I had the view like in the screenshot.
What do the switches mean then?
I open Roon and select music from Tidal. Then I play this and then have the mentioned problems
In the screenshot you can see once exactly that nothing is activated. But if you then click on the song title on the dot appears the windo, which you mentioned. This is not all conclusive
Is there somewhere a way to free the whole system (MAC) from Roon? Total Reset?
As, I mentioned Volume Leveling is under the actual Zone setting and not with the other DSP and not subject to whether or not anything is enabled or disabled there. This is the place you can turn on/off volume leveling, nothing you do on the DSP page will affect it.
