Hey WiiM community! 
I've been testing two different versions of WiiM amps side by side and wanted to share my findings while inviting others to discuss their experiences. I have detailed photos and qualitative feedback from my testing, plus some interesting API response data that might be useful for the tech-minded folks here. What was most interesting to me was that the v7 Amp is running a 5.2.x branch of firmware (which is seen in Amp Pro / Ultra), but the 5.x.716363 is the similar across both branches, and no noticeable difference in sound quality so far.
Here is the difference in the API status pulled from these two amps, and more qualitative differences highlighted in photos.
Have others noticed similar differences between versions?
Would you like to know anything else in particular?
