I upgraded my system with a Keces P6 LPSU. It provides power for the Sonos Port and Intel Nuc11 Core i7. Surprisingly, the sound is a bit cleaner now, so it will stay. It provides enough power even on DSD512 upscale.
All my system components are listed:
1. Keces P6 (lpsu)
2. Intel NUC 11 i7 (Roon ROCK)
3. Topping E70 Velvet (Roon to Sonos link, sounds better and more stable than native streaming using Sonos protocol)
4. Sonos Port, Five, Sub
5. Samsung ViewFinity S8 4K HDR monitor + Chromecast Ultra (Roon Display)
