Any carrier (FedEx, UPS, USPS, etc.) is only as good as the employee handling the package at any given stage of the shipping process. I have had more bad experiences with UPS than any other carrier, and that's probably due to the luck of the draw.But I do believe a greater percentage of FedEx drivers are more cautious and conscientious than Brown's. As far as damage in shipment goes, the largest factor in preventing that is proper packing, which on heavy items has to include double boxing if the original packing materials are not available.
I bought an older pair of Boston Acoustic speakers a few months back that had to be shipped from MA to NC and was worried about damage. Although the CR7s were just over $100 including shipping, the seller packed them so well it took me
almost 30 minutes to get them unpacked (several different packing materials were used and each speaker was individually wrapped/cocooned in plastic sheeting). Turns out the seller actually worked at one of the major speaker manufacturers back in the 70s or 80s, although he didn't say which one. The lengths that he went to in packing these modest speakers was amazing. Careless or incorrect packing is usually more of a culprit than rough handling, especially in used equipment scenarios.
