I am 9 pages in to the review and no one has mentioned one of the greatest aspects of the WiiM family of products. All of the WiiMs as long as they are on the same network can be linked together to create multiple music room environments all controlled by your phone app.
We are building a new home and I have already identified 6 zones where I want music: family room, bedroom, den, outdoor room, by the pool, workout room. Each of these rooms will be a "zone" with it's own WiiM located in my electronics closet. I will be able to choose music for each zone, the volume etc. They can have the same music or different music.
Yes, this is available in commercial systems for big money on complex set ups or using SONOS for 3x the WiiM price. But with these little and relatively inexpensive WiiMs, I can set up many zones and manage them all with an app or have a cheap tablet in each room for control. I can use the higher quality WiiMs where sound matters and the cheaper ones where I just need some background music and they all work together.
I see this as a breakthrough for whole home sound systems.
