The Classe'is rated at 150wpc and the Sim at 70. But, I never wanted or needed more power from the Sim. It just seemed to be more powerfull than it should be. I think the two are both very good. I do think I still might prefer the Sim over the Classe', but I did go from Acurus to Sim which was a good jump. Now I am comparing the rig that replaced the Sim to the Classe'. Hey, if your in Texas (I'm in the Fort Worth Dallas area) you'd be welcome to come have a listen. And I am going to sell the Classe' if you'd be interested?? What's most important is how it sounds to you.
