I got myself a Wiim Pro, hoping it should be superior to my WXC-50 / MusicCast. Got it a month ago, have had ample time to evaluate (without any measurements). This is then from a typical user perspective.
The WXC UI is much better than Wiim UI, in particular when playing music from a NAS. With MusicCast one gets thumbnails/ pictures / etc in a good way - Wiim UI hardly present any such, in particular when there is a folder with only folders (trick is to put an empty playable file (as music.mp3) in each folder, which is great fun when one is having 1000:ands folders. OK it can be done with a one-liner in Linux CLI, but to have 1000:nds of empty files is not attratctive).
As of today, Wiim and WXC are rather equal when it comes to streaming.
I do not have a separate DAC, thus using the included DAC:s in Wiim and WXC. Rather equal again in sound quality, provided both are set to flat / direct / fixed volume. As I only listens with loudspeakers (no headphones), I am not convinced a separate DAC unit, however good, with improve the listening (I might be completely wrong here, happy to see arguments).
Wiim as a rather new product have some problems. Some of the files on my NAS Wiim cannot play, but WXC has no problems (one typical such file has been downloaded with yt-dlp from youtube, and is characterized as "MP4 AAC 16 bit 200 kbps 48000 Hz 2 channels 1:22:06). Standard Linux players have no problems with this file, but Wiim has.
Thus, for the moment, Wiim Pro has not been a success for me. If Wiim improve the UI and implement some nice features as PEQ, that may bring Wiim in a better position. Would be nice if the distortion issues like those related to utput lervel could be solved but I fear those are hardware related. Somehow I get the impression that Wiim and others master digital design and maybe software whereas analog design is not so easy.
