It is highly likely the SPL limits of the Paradigms that are exceeded that caused the damage. The user controls the amount of power delivered to the speaker via remote, and the fate of the speaker lies in the wisdom of the listener when turning up the volume on the amp.
Several months ago my tiny Paradigm Titans were destroyed with too much power applied so I chickened out trying it again.
In other words, too much power on a powerful amp is not the cause to the destruction of the Paradigm Titans. It is the amount power delivered to the speakers which the user has control upon that damaged them. To avoid this, a speaker with higher SPL ratings/capabilities will be more appropriate(usually big speakers with large drivers). Otherwise, avoid listening to music at high volume levels. The Dynaudio Focus 140 may play louder than the Paradigms but still you have to practice caution when cranking it up. Pay more attention to the excursion of the drivers and distortion in music if you don't want to damage the speakers with your powerful Classe amp.
