Hmmm, then it is very misleading that Yamaha would put the x7 after the 120W full frequency RMS rating their manual says it has. But in growing up with H/K, I know their quality is rock solid, but they have always charged more due to their name. In fact, you can get factory outlet receivers (much like here at axiom with their factory store) for a discounted prices. So, I have a feeling the way they are rating their output is similar.
