I learned the hard way to keep the original boxes wherever possible. Not only do the original boxes perfectly protect the equipment and have styrofoam inserts that perfectly fit and therefore protect the equipment, but to have expensive gear, especially speakers, packed in new boxes and bubble wrap is pretty pricey itself. And if it isn't done right, you get a mess when delivered. That has happened to me twice, (receiving and selling) when I lived in a condo with minimal storage space. Now that I am in a house, every box has a nice storage spot on shelves that I built along the ceiling of the garage. I'm not sure that I would pay less without the original packing, but it is definitely a selling point.
