And this lab test of Denon's 3808 shows it does achieve the rated output all channels driven. I think many of the new avr's now do indeed meet an all channels driven spec, at least most of the ones I have recently seen tests for. Yes, they are at the 1% THD threshold but still achieve the rated power output. I know many of the seperate amps achieve the rating with well below 1% THD, but even at 1% I doubt most people would hear it.
