Yeah, I can't say they were lying about the XT's *******, because they just about practically said it in the video that one of the members made interviewing the guy. He said something to the effects of
"no the XT line isn't CES rated and we put that number on the front because people want to see a big number or they won't buy it"
Older U.S. amps = A+++++ Newer AX stuff = A+. Anything else, ask flakko (name right *ponders*) as he has direct connections and has never done me wrong. I have 2 US amps in my basement right now collection dust. The one is a newer model that I use if I am having upgrades done to the tru, the other is a sub amp that pushed the hell outta my W3 years back.
