I have the Expert 400 powering Wilson-Benesch Vectors and was controlling it with both the remote and the iOS app via an iPhone X. The source was Spotify and the volume went from silent to full on without warning. The app showed the volume to be at maximum and was in the red/+30dB. It played very briefly, (milliseconds?), and then shut down on its own.
