I just find this... and as a user of B&W (all in one + even streaming) Formation Duo,
I remember that I‘m surprised at the sound quality - the advantage of all in one design...
the designer know what they pursue and get it done in a right way.
The possible problems are basically two kinds from my experience.
1) You have to settle with one sound. (good for some, critical limitation for some)
2) If there is trouble, you have to deal with the whole unit.
#1 wouldn’t be a problem if the user likes it. #2 wouldn’t be a problem if the user has tons of money.
But for me, because of #2 reason, I don’t want to.
Also there is no way to distort sound later for any personal reasons.
Also not sure about other people, but for me, one of major reasons I buy B&W formation duo is its clean look. (No wire, no something around)
And good look. D&D 8C looks okay but personally not 10k good.
If I had this much money I would get Avantgarde for a living room, and honestly not care about the graph.
It would be like buying classic maserati quattroporte.
(And my one of the other sound rooms maybe ATC or Genelec, I don’t know)
