Phantoms and RAAT

[ogs]

I use a rpi4 with RoPieee myself and that would certainly work with Phantoms with an appropriate HAT, however this must be considered a workaround compared to RAAT direct. Devialet has indicated they will have RAAT with Phantoms.
The Devialet Expert amplifiers have had RAAT for some time now and that works very well (apart from those that have trouble with RAAT and 1GB connections). With DOS1 and Dialog I guess Roon works well, but if one buys new Phantoms today they will be delivered with DOS2. Ethernet sounds better than Toslink (I've heard) so with DOS2 RAAT would probably be the way to go.
