Hi Bill
They work with Roon, like Sonos and Linn, but from memory I don’t think they support RAAT (though could be wrong as I do not own them).
Soon you should Have the KEF LS50 Wireless 2, Buchart A500 & A700 (towers) at least fully RAAT supported, but neither is Roon certified yet so buyer beware (hopefully in the next month or two). Roon does not pre announce until certification is complete unlike the manufacturers who seem to pre-announce Roon ready many months before (and longer).
There is a thread from a few years ago here
