80 lbs isn't that much for common carriers such as UPS or Fedex Ground as long as it is properly packaged. I would use the original boxes and have it reboxed in another box with large bubble wrap or foam all around the original box; don't ever use peanuts.
Obviously, shipping LTL on a pallet is going to be the safest way but will cost about double what regular ground shipping will be and would affect the sales price of the amp if you take this into acount as the buyer may be reluctant to pay for LTL palletized shipping with liftgate service.
Both UPS and FedEx are in 'tight' mode due to the economy and are very reluctant to pay claims. If you do ship it common carrier, I would take pictures of the original box, the amps, the amp in the box and the second box with the foam in it just in case something happens.
I worked at FedEx for 20 years. My 2 cents.
PS-Anything over 100 lbs I would ship by LTL pallet.
