For an Airplay speaker it is a great system with a decent sound, but not as good as a normal stereo setup, like Peter from Denmark said in his review.
Maybe he works for B&O... maybe this is why he mentioned that the A9 replaced Bowers & Wilkins and Denon equipment...
But back to the system.
Setup is easy, design and build quality is good but the sound is not worth the nearly 3k. I listened to the system at a B&O store in Hamburg.
It can fill a large room with sound but mono sound. It even become a little unaccurate at higher volumes like the Beoplay A8.
To say it clear 2 middle priced bookshelf speaker around 1k and e.g. a Marantz Melodie Media which is also Airplay capable performs better in clarity, volume and Stereo separation for less than 2k.
If you need the all in one design, go for an Zeppelin Air or the Marantz Consolette and still saving 2k without loosing sound and power qualities.
If you're a B&O lover go for it instead of the Beoplay A8.
