Try contacting a professional packer and shipper who will take responsibility for damage during transit.
packing and shipping
I have a McIntosh set consisting of 2 MC-30s and a C-20 preamp that I want to sell, I'm concerned about the weight if I have to ship them. What's the best packing and who is the safest shipper? My first post, one of my clients said this site is the BEST for serious audio people, so i figured you guys would know.
