I've shipped, and/or received 100+ audio items over 20+ years, and have not had a single issue of damage (either sending or receiving). I have had a few boxes arrive in pretty bad shape, but luckily no damage to the item.
I tend to over-package anything I ship. The original factory packaging is typically not sufficient, especially if it has already had multiple trips.
Double boxing, added foam and plastic cling-wrap are your friends. Any possibility of an item moving in shipment, even if just a little bit, is a recipe for damage. Use enough structured foam to insure zero movement, even if the box is dropped on it's corner. Wrapping the item tightly in plastic stretch/cling wrap prevents scuffs, even better than the original factory bag/wrap
I buy foam sheets from Home Depot or Lowes, and use a large drywall square as a straight-edge for measuring/cutting the foam. I'll usually buy 2 different thicknesses that can be used individually, or stacked to create 1/2", 1", 1-1/2" and 2" barriers, as needed.
Do yourself a favor. Over package and prevent the hassle of a shipping damage claim.
