Don't believe that Onkyo rates their power the same way that Panasonic or some of the other cheap receiver companies do. Onkyo under rates just as much as Outlaw does. For example I have an Onkyo 595 and I was worried that it would not be enough to power my speakers because it is only 75 watts on each channel. Well, no problems here it powers my speakers just fine and I have no problems.
