I concur. I have owned WiiM Ultra as well as both, Eversolo T8 and Eversolo DMP-A6 Gen 2, and none of the three were hard to use at all. Yes, it is disappointing that the DSP cannot be applied to alternate sources (such as ARC in or any of the digital or analog inputs) and only to the internal streamer, but besides that functionality issue, usability, I found, was excellent for all of them.
Heaven forbid he be presented with trying to get moOde set up on a Raspberry Pi and then getting the Roon bridge installed via BASH/SSH terminal!
