Indeed........... there is generally a capacitor across the power switch in some manner or another that takes 'surge' when the switch is either turned on or off. Could be bad or a cold solder joint.
Have you tried with another set of speakers to confirm it is only with the Focals? That would be an easy check before going back to McIntosh.
