McIntosh Double Box?

Hi , May I ask an off topic question please. My friend has this preamp paired with the Big Mac SS monos powering some big B&W’s. As I’m a tube roller but with zero experience with Mac, have any of you rolled the tubes in this particular unit ? He does not have a TT, but streams and spins CD’s. I went over to listen and he asked me about tube rolling. FWIT he loves the sound of this combo with the Diamond tweeters , but I thought it to be a bit bright. Thanks , Mike B. 

I have heard in the past that getting remuneration from shipper such as UPS and FedEx can be like pulling teeth, and that USPS, unbelievably, is better.  Since you insure your parcel for a stated amount, is this a big deal or not?  Let's say you are mailing a paperback book to someone and insure it for $1000.  Does that work?  I'd be interested to hear from someone who's shipped an expensive piece of gear, labelled "electronics" or something and experienced damage or loss with one of these shippers. How has that turned out?  And yes, find a way to hang onto that big box.

When one tries to sell or ship, original boxes are ideal. Storing these boxes can be challenging.
