Another vote for "Denon receivers have decent power and lots of features but are horrible to set up". HK receivers have tons of power (despite being rated for maybe 1/2 as much as a comparable Denon), a very simple UI, and almost no features other than the ability to set different crossover frequencies for each set of speakers, which is really cool.
