I have spoken to a few people who have said DHL is much better than FEDEX or UPS.
Supposedly,  they are much better with their handling and treatment of packages.  These guys I spoke with praised DHL and they both had used DHL extensively for shipping Audio gear,  which included heavy power amps.
I haven't tried them (DHL)  myself,  but I'm  considering asking Klaus,  when I order my Mono Extremes,  if he would use DHL;  even if I have to paymore money for the shipping.
It's something to look into.
