The app that I envision would make multi-room more central to the experience, and provide access to sources in more unified way. This would reduce the steps needed to get music (or other media) playing on one or more devices, as well improve visibility into what is going on inside your home at any particular time. I believe that if this is done right it will elevate older products instead of having them being treated as an afterthought, which seems to be the case with some of the early NL devices, such as the NL/ML converter. I also think there is room to add integration for some third-party products so they may be used as sources, as well as possibly absorb some of the functionality of the Beolink app.
The reason I’m making this post is to get a sense for whether folks here would be interested in such an app and whether they might consider paying for it. Folks regularly post feedback in response to updates to the official app on this forum and I think it’s unlikely that anyone at B&O is taking any notice. I can assure you that I would, especially if you were paying for the privilege.
