I good place to start would be to email Panamax. I did this when I was comparing the Panamax 5100 vs Monster 2600. I got one heck of a responce comparing all the nuts and bolts of the two. It was a multi pagesresponce that was definitely writen to answer my specific questions. I have not purchased either unit (YET!!!) but it sounded like the panamax puts its money more into the actual protection components while Monster is more in the glitz.
