Yes, the double box-in-a-box method with foam around component in inner box, foam around inner box in outer-box--this is about the most surefire packaging and I know that Levinson, Cary, and McIntosh all do this. Always arrives in one-piece even if the outer box gets dinged up.
But best packaging is w/o a doubt Jeff Rowland amps--foam on all sides around amp (which itself is in a velvet bag), that inside a hard metal flight case, which itself is surrounded by foam and contained in an outer box. Superb packaging. Bullet proof.
I also like guys that use hard wooden crates like Lamm, again, very hard to get shipping damage in that case (tho not impossible).
