Loud pop/crack in speakers from PWD

I have a Perfectwave DAC MK II with a Bridge II. All firmware is up to date. This is going into a Pass Labs XA30.5 amp via XLR cables powering Tekton Pendragon speakers. Whenever the DAC changes functions there is a small click inside the DAC followed by a loud pop/crack through the speakers. For instance if I change input from USB to Bridge and back. Or if the song format changes (flac to aiff to mqa). If one album is flac the whole album plays fine. But if the next album is aiff the crack happens as it switches file format but then the rest of that album plays fine.
I’ve sent it in twice and everything checks out fine. They say it’s because the Pendragons are very sensitive speakers. Anyone else ever have this happen?
