To go multiroom, or to have your inputs remote from the wireless speakers, Dynaudio has two main options.
The Xeo Hub has two analogue inputs plus optical, coaxial and USB digital inputs; it supports files up to 24-bit/ 96kHz but transmits to the speakers at a maximum of 16-bit/48kHz.
In our testing we used the higher-spec Connect, which has the same inputs but adds a Wi-Fi connection to your home network, enabling DLNA and Spotify Connect, plus Bluetooth. It can stream at 24/96 to one speaker pair or at 16/48 in multiroom mode to four sets of speakers.
Then there is a Xeo Extend, useful if you need to increase the range to reach far-flung Xeo speakers, and a Xeo Link, which receives the wireless output of the Xeo Hub and can output it in analogue or digital for any audio device to replay.
