You really think the main reason people are buying WiiM is for 24/192 multi room playback? How many of those people could honestly tell the difference? I have some sympathy with the argument that if you’re sitting down focusing on the music that you might want to have it at the highest resolution (again, I’d debate whether many could hear the difference), but when you’re playing music in multi room “party mode” wandering from room to room, 24/48 is arguably more than sufficient. Again, I won’t deny some come to hi res music chasing ever higher numbers, but most soon realise that the quality of the source recording matters much more than the numbers on a screen.
