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.
