I just ordered 3 of three channel unlts.
I spoke with their rep and they are getting airplay2 loaded in via firmware the next few weeks.
I was waiting for a whole home clean solution (without chromecasts or airport expresses hanging all over it) with AIRPLAY2.
airplay 2 is the absolute best plan in my view because we are already on our phone all the time.
On the phone is where we do our library functions for our music (such as adding to our library or working on playlists).
Voice control via homekit/siri is somewhat useful as well, but really a GOOD connection via the phone and a great wifi network is ideal IMO.
I love the fact that it has a 7 band PEQ as well which can be helpful in making some basic adjustments to bass response when you are using in-ceiling speakers. Audyssey or Dirac (basically a mini-dsp) would be even better but really I don't spend that much time nitpicking my personal total home system.
If I was building a new house with a subwoofer in EVERY room, I might want a more cohesive bass management system.
I think the PERFECT product would be a merge between VSSL and MINI-DSP with sub outputs for every zone. We are likely getting nothing of that sort any time soon or a mini-dsp with airplay 2 on every channel so I won't hold my breath.
In the meantime, i am excited to take delivery of the 3 channel VSSL unit. I ordered two for downstairs and one for upstairs. I decided not to buy the 6 channel because the 3 channel looks better on my rack (vain I know) and the 3 channel is easier to separate if I want to split the location of my actual amplifier. I like the fact that it is class D, quiet, fanless. These are all critical features for me. I like the cohesive app and the fact that I don't really have to tweak it once it is fully setup. Once I EQ the thing (with some room measurements to help), I really don't have to touch the thing again.
That last point is why I have moved everything in my house to homekit and airplay2. Now, almost everything in my house will be airplay2 or homekit compatible. The ONLY gear that is missing from that ecosystem for me now is the Door locks and the security system and doorbell. I am waiting for coherent products to emerge before changing all that just yet. I suspect in a year or so, everything I want will have been invented and released.
I used to have a control4 but they have taken FOREVER to update to airplay2 and have not done so yet. On top of that, they provide no roadmap to when that is going to happen. And then when it happens, I have to pay a dealer god knows what for updates and service calls. Homekit with voice control is a definitely viable alternative to all that complexity.
