EMM Lab CDSD transport motor resonating

Has anyone experienced any sort of resonating sound coming from their CDSD when playing certain CDs. This has happenned to me on two discs, the latest one with "Shirley Eikhard - Stay Open, Track 1 - Take It To The Max". I assume it has something to do with the rotation speed of the transport on that given track, because it slowly fades away past the 2 minute mark, and doesn't occur on any other track. It is extremely annoying and surprising for a $7K transport. I'm starting to wonder if I need to send it back, but I'm hesitating considering how difficult it has been to get it in the first place.
