Anything that supports RAAT is the standard for Roon playback. Many people use raspberry Pi devices to give themselves RAAT capabilities on their dacs and activate speakers (so Ropieee or VitOS, or Hifiberry OS if you use a HAT for digital or phono out)
RAAT compatible speakers tend to run into the thousand’s of $$$
I have used Pi’s and currently a Matrix Audio streamer to drive my Sonos Amp via RAAT
Thanks Mike - is there a list of RAAT compatible speakers? Aren’t the Bluesound speakers RAAT compatible? They have something nearly identical to the Sonos 5, which I can just sell or give to my mom as another alexa speaker.
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).
