Yes, the 400xi doubles it's power output into 4ohms. It's very odd when someone attacks a brand so feverishly. Especially when the attacks are broad baseless remarks. I like the 400xi at it's price point. Any number of other products exist that can generate great sound as well. What's the problem? Components are only as good as the system and environment allow...just as many people will line up to praise one component as another. Audiofeil is all about Audiofeil and whatever his inventory holds. FYI, several reviews of the 400xi have been done over the years...check them out and listen for yourself. If you don't like it then go elsewhere. DKzzzz seems suspicious to me based upon the lack of detail put forward in his rantings. Normal individuals who review something explain their results, mention how they used a component and even note what music helped them to make a decision. I believe DKzzzz owned or owns Sonus Faber speakers..funny he should bad mouth them. By the way, the Krell KAV400xi offers unprecedented power and control for it's class with a pure Class A pre-driver stage, Current Analog Signal Transfer, a massive toroidal power supply, fully balanced circuitry, surface mount circuit design and remote operation...gee, I geuss it isn't innovative at all is it! I'm sure some standard old fashioned, underpowered, conventional tube unit from some online hack would be far more innovative.
