ML 383 High Power shutdown

The ML 383 integrated amp has a High Power protection circuit that shuts down the amp when a power spike is detected. I recently moved and am now experiencing excessive High Limit shut-downs ( multiple per day).
Is a power conditioner the answer??
Contact Madrigal, if it is an earlier unit, they have opened up that "window" to not be so touchy on later units. If this is the case with yours, you can take it to your dealer and they can download the change to yours.
Thanks Brian! I will contact Madrigal as you advise.
