We use a streamer ND5 XS2 and a power amplifier NAP200DR. This combination works well, even better than with a full amplifier Supernait.
But here it is necessary to regulate the volume of the streamer. This one goes
(A) with the Naim app. Even if the music is played by Roon.
(B) the streamer is connected to Roon via “Airplay”. Everything works, but HiRes Audio is not supported.
© The stream is connected via “Roon RAAT”: The volume is not adjustable in Roon. Although device volume is selected instead of fixed volume during setup. The last set volume of the streamer is played. In Roon the message appears that the volume can not be regulated. However, in the Naim app, you can be customized for this playback.
Since the device has no external volume control, this state is permanently intolerable.
