My setup provides audio throughout the house for casual listening -- listening while making dinner, lounging in the living room, relaxing in the back patio spa, or having people over for a drinks and fun. I have built and configured it for the ability to move music from one area to another, or to group different areas together to play collectively. It has replaced a similar Sonos setup that I ran for over a decade.
Sound quality is important to me, but within the reasonable bounds of the type of listening I am pursuing. I primarily stream flacs from my home NAS, as well as stream from Spotify.
Main floor kitchen / living room
WiiM Pro Plus analog outputs feeding:
Emotiva BasX A4 4-channel amplifier driving:
4x KEF Ci-200MR in-ceiling speakers (stereo pair in in the kitchen, stereo pair in the living room)
WiiM Pro Plus analog outputs feeding:
HTD SDA-200 subwoofer amplifier driving
HTD Sub 80-LP
This is our primary living space, which is effectively one large room, and I've put the most effort into this area. The four KEF in-ceiling speakers give excellent coverage. The pair in the living room actually work pretty well for more engaged listening as they are arranged pretty well relative to the sofa. The KEF drivers have great dispersion and I think are perfect for this job.
Because the kitchen is a very live and "bright" space, I have attenuated the analog inputs to those speakers via 3db rca attenuators to better match the levels in the living room.
The Pro Plus and 4-channel amplifier live in a cabinet in the kitchen with the network stuff.
I recently added a little low-profile passive "subwoofer" and digital amplifier under the sofa. This is driven by a second WiiM Pro Plus, effectively turning it into a networked sub. I keep it grouped to the main Pro Plus feeding the in-ceiling speakers. After a couple weeks of adjusting, listening, and tweaking, I am very happy with the way it fills out the low-end in the room, and actually gets the room thumping with the right music and a little volume. I think there is opportunity here for WiiM to enhance this kind of usage...
Basement home theater
WiiM Pro Plus digital (fixed) coax output feeding:
Denon AVR-X6700H driving:
7.4.2 speakers consisting of mix of Elac Uni-Fi Reference (center channel), Elac Uni-Fi 2.0 (L/R), Elac Debut 2.0 (wides), SVS Utra (surround), Elac Debut 2.0 (height), and a couple HTD subs (12" and another little low-profile).
This is our cozy place to retreat into movies, tv, video games, and occasionally some focused music listening. The WiiM gets used for focused listening or when have a party and group it in with everything else.
Basement shop
WiiM Pro Plus analog outputs feeding:
Parasound Zamp V.2 driving:
Elac Debut 2.0 DB62 bookshelf speakers installed in the ceiling
I spend a significant amount of time in here working on bikes, skis, assorted projects, and I like to drink beer and rock out while I work. With the way I have finished the ceiling in here, I have hidden a pair of bookshelf speakers behind slats. Not a great for sound dispersion, but it works well enough for me. These also sometimes get grouped with the rest of house when we're feeling festive and social.
Back patio
Audio Pro A10 MkII (non WiiM edition) x2
I have two A10MkIIs set up as a stereo pair on my back patio. This usage is officially a little out-of-spec for being installed outside, but I have accepted that as my choice with my consequences. I am not concerned however, as they are under an eve, and I have done some customization to protect them even further. I did the same with a pair of Sonos One's for over 10 years without any issues.
These do a great job filling our small patio with sound, and when the weather is nice we can be in-and-out with contiguous music on the main floor kitchen / living room area.
Bedroom
Audio Pro A10 MkII (non-WiiM edition)
Last but not least I have one A10 MkII on a shelf in the bedroom. It occasionally gets moved to the garage or the front porch. We call it our "portable" speaker.
I am very happy with the WiiM products, software, and most importantly their support for their products.
