Here’s a comment
I know testing a streamer is very complex. I am now using the Aiyima Hifioo DM100 streamer and I simply love it. Its open deGoogled Android 14 is great. I can install whatever I want, it has no Google bloatware or spyware and has the same CPU as the T8 and the RAM of the T10. It has an internal SSD bay and most important: it has an HDMI output. It can display 4k on my big screen. Great for watching your video without the stupid annoying youtube ads. It has a USB output which is all I need for my DDC. And it only costs $530. 
My Rose Audio streamer started to get really annoying. Updates are slow and sometimes stop certain functions from working. The apps are closed source so you are totally dependant. And if they stop support you’ve got an expensive boatanchor.
