Wireless is a hot mess. I don't see any opportunity for an open standard in wireless audio transmission beyond BlueTooth. The average consumer has no patience in pairing and troubleshooting dropped BT connections. Every one else (KEF, Sonos, Bose, Enclave, etc.) have their own proprietary wireless standards that lock you into their ecosystem.
I do like the idea of less gear though. Minimalists like myself are enthusiastic about adding lightness through heavy hitters.
