A suggestion from Doug at That Fish Place in Lancaster, PA has proven a good solution: take come sand and place it in a small Ziplock bag. Place that under the pump.
This worked at real well, as I hadn't yet opened the new bag of Special Grade Reef Sand.
Of course, replacing the impeller in the brand new but defective MagDrive 7 was also helpful. The original impeller had chunks missing! F&S sent me a free replacement.
Simple and cheap solution to use the sand and Ziplock. And, I also placed a 5/8" section of pink insulating foam (used in construction) under the sump. This serves a dual purpose: helps insulate the sump from a cold floor and totally deadens transmission of vibration from pump through the sump to the stand, etc. Only remaining vibration is transmitted via the plumbing return (which is minimal but there).
