So, I give my experience with the A10's WiiM editions (& Non WiiM) after about a week with them.
As I've stated elsewhere, I’m replacing my entire Sonos multiroom setup and doing the WiiM thing. So far, I liked the WiiM mini so much that I upgraded to the Pro Plus only after a few days of use. I set this up in my den with a new record player and a pair of Audioengine HD3's and a Cambridge Audio Minx X201 sub and the sound is fantastic.... Could not be happier with this setup, the WiiM devices work great, no issue with streaming music or sending the turntable audio to the other Wiim Speakers, mission accomplished.
Now setting up the two A10's (WiiM editions) worked, but was a little flakey. I felt like too much fiddling with the phone was required (connect to speakers wifi, turn off phone data, etc...) it worked but for each speaker I received a never ending-spinning-connecting ring which required closing the app manually after several minutes and letting it start again and then it was connected. Not sure about spinning "connecting glitch" but whatever, it worked... Phone is a S23 ultra which gives me ZERO issues so I can't blame the phone.
So as for the sound (which is subjective) .... I usually sit at my dining table with my laptop and listen to a single Sonos One that's about 5 feet away from me, low volume, background music and I could tell immediately that the A10 lacked the low, warm sound of the Sonos One... It's just not there, no two ways about it. And yes, I did the room tuning.
Regardless, it still does sound pretty good and it does get loud and sound crisp. I would say this speaker does much better at a higher volume so when I decide to play music throughout the house, it's perfectly fine. I stuck the other one in my Master BR and its sounds great in there, wife is happy with it. I'm still speaker shopping and will try to find one that does better with low volume sound quality for my Dining room.
So the other pair of A10's (non Wiim) I ordered turned out to be a complete disappointment... These were supposed to replace my pair of Sonos Ones in my family room. I set these up through the Audio Pro App this time and had the same spinning-connecting glitch, shutdown the app manually, restarted and they were connected. Shesh....
I grouped them, separated left and right and then discovered each physical volume button does not become the "Master" between the two, it only controls volume for that specific speaker... WTF??? So, to clarify… even though they are grouped/paired L/R, If you want to control the volume between the two you have to use the app, the physical volume button only does that individual speaker... Just WOW.
The point of speakers in this room is to keep it simple so someone can walk up to the speaker and control the volume (regardless of L/R, just like the Sonos ones) and use the favorites button which was a major plus for the Audio Pro's. But the volume thing is so dumb that these are going back and will be replaced with a single Audio Pro C10 (WiiM edition) to hopefully keep things simple.
So at this point i'm on the fence on how I feel about Audio Pro as my "replacement brand" for Sonos. I really don't see much hype for them, shopping for the speakers from Amazon was a bit confusing at first between models (Wiim, non Wiim) and then I see several complaints regarding customer service (or lack of) and the Audio Pro app itself seems to always be lacking.
