I am building a master bedroom suite with a small home theater area. I would like to use in wall speakers and Sonos Amps and a subwoofer for the system. However, I understand the Sonos Ace headphones will not work with the Sonos Amp. Is there a plan to upgrade the Sonos Amp in the near future to be compatible with the Ace? If so, I could proceed as planned and just switch out one of the Amps to the newer model when it becomes available.
