I have to make my voice heard in this too. Can only agree with what everyone has already said that the USP that B&O has had for many years is about to disappear. I became a customer for ease of use and that it was possible to build systems of their products. The stability of the system has disappeared and system thinking is on the way. Then there is only design and good speakers left.
Many have raised the point that "touch to join" disappears, but the biggest limitation is that the source is moved from the product to the phone. Today, the radio switches on in the kitchen in the morning and then it is on regardless of who is in the kitchen. If I want to listen to the radio in other parts of the house I use "touch to join".
Many have already written how they are considering other systems and I myself am completely on Sonos, but keep B&O's speakers in large rooms. It will be an investment and as someone pointed out that the older products with ML become obsolete. Can be considered, but it stops new purchases of B&O until I understand better.
