Well this will get some people stirring no doubt.
From a HT Mag review (lab test sections) the "all power driven" ratings of the H/K is actually above that of the Yammy (in 5 channel mode, since the 147 is not a 7 channel receiver). Of course the Yammie is loads more powerful when pushed harder, but at typical (reasonable) listening levels the H/K is a force to be reconed with; especially at that price point.

Of course I realize they are in very different categories as far as receivers go but hey those H/K units really shine in delivering quality power and are very reserved as far as power ratings go.
I really hope Tom, Clint or Gene review some of the new H/K offerings. Many look at the H/K units as low powered and overpriced receivers. They really just rate the units conservatively (no BS) and don't tend to have the marketing penetration that others do.
This was in no way meant to bash Yamaha, only to open some eyes and raise some eye brows.
