Thanks Ravsted. Unfortunately, my router only broadcasts SSID, not SSID_2.4GHz and SSID_5Ghz. I might also have a hard time convincing all of the locals to switch their phones to not use 5GHz... as the 2.4GHz spectrum is pretty crowded. I do see my CCA is connected to the 2.4GHz network while my other CC devices are using the 5GHz. At the moment, everything is working just fine. A few hours ago, the CCA was not to be found. Then again, I am broadcasting to a group while writing this, and it stopped midstream and needed to be restarted. I don't have the problems with NL.
MM,
Spotify and TuneIn (netradio would work, and could be better since one of my favorite stations has left TuneIn, but still works on my BS5's netradio) are my primary use cases... although I'd be willing to use Deezer if the user experience was better. I mostly use Android so no Airplay, but my wife and kids do use AP from time to time. I do see value in NL as I would like to sometimes broadcast my Eclipse audio (from the TV program, not the SoundCenter). This is really a nice to have vs requirement, but if I'm going to upgrade and spend more than ~$500, then I might as well spend some more to get this.
For those bored and sitting at home, let me tell you my full story of how I got here:
My real issue is my speaker in my kitchen. I have a BL3500 connected to my BS9000 (in another room) which my CCA is connected to. The kitchen is where we often hang out, and my wife and I like to listen to music when we cook. My wife has given up on the CCA and gives me the business about how I have "all this fancy B&O, but it doesn't work". I explain it's really the $30 CCA, but she doesn't care. She just remembers the fairly frequent experience of trying to cast to the CCA, and it's not there. We have a little Alexa device that was free with our doorbell which she is now using for music in the kitchen.
My original solution was to replace the BL3500 with a BS35. This would be an upgrade in the sound, and should be easier to use. However, in searching for a BS35, a dealer strongly recommended a Stage instead (newer software, much better sound, similar price) even though he had a ex-demo BS35. However, my wife prefers the smoked oak, and this will require a new remote and some electrical / wall work to move the outlet for the Stage. I know this will sound much better than the BL3500 (and BS35), but the oak + remote + install work makes this quite a bit more expensive, and the Stage might be overkill for my relatively small kitchen (small by US standards (14 X 16 feet), probably quite large in the rest of the world).
Enter the Level. Almost bought one yesterday. Wife can talk to it just like the little Alexa, and I will no longer die inside hearing music from Alexa. However, I'd like to be able to link it with the BL3500 for parties (some day when we have parties again), and I have no faith in using the CCA with speaker grouping. It would also be nice to get the TV sound back in the kitchen (something we gave up when we swapped out a BV for the Eclipse).
This brings me to the Core. If I swap out the CCA and replace it with the Core, then I get (hopefully) more reliable streaming and TV sound (delayed) to my kitchen. If and when the Level gets NL, then I can add that to the mix, and use the Level for most cooking (which also probably sound better than the BL3500), but still have the BL3500 when I need more coverage... Or, I can just get the Level because it's new and cool, and seems a lot more fun than a Core :D.
