If the static was induce by the motor it would happen all the time just not when playing "Test Tracks"
On the other hand it may not be an issue with the Integrated, it could be that the CD players you use can't decode/filter the particular tracks. Does the particular issue happen only with this integrated or have you tried it with other amplifies as well.
But, how important is this really, I presume you bought the integrated to play music, not test tracks- so why worry about it.
Good Listening
