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.

It's usually said to be a problem with the batteries of the remote - change them for new and it should not happen again. There is also a suggestion that the D400-D440 upgrade also includes some work on the remote to prevent this occurring.
I see you have WB Vectors - which have a SAM profile - did you have SAM active? If so, then there should have been some protection for your speakers. I hope so.

It wasn't a battery problem for me, the remote needed changing. When they sent me a new one I kept the old 'problem' batteries, they were fine in the new one.
The problem has never happened with my new remote.

I turned off SAM because it did not sound as smooth in the bass registers as without. I did have the subsonic filter on. I'll change the batteries just in case. Thanks!
