The good news for MisterBG is that the Beosound Moment has inbuilt WISA that will transmit to WISA wireless speakers – some of the newer Beolabs have WISA receivers built-in. In order to provide the WISA facility for older speakers, B&O introduced the Beolab Receiver 1, which acts as a WISA receiver and provides a Powerlink output to Beolab speakers.  One Beolab Receiver 1 is required for each Beolab (Left and Right). However (as Beobuddy has just pointed out) the BL5 is incompatible with Beolab Receiver 1.  This is explained in this thread, in which Steve also suggests a workaround making use of the BL5s’ Line inputs: https://archivedforum2.beoworld.org/forums/p/25222/201651.aspx#201651 So MisterBG could either buy a couple of Beolab Receiver 1s and use Steve's workaround, or stick with the wired solution.
