tlong1958........What you said is so not true to me. I DONT have alot of money buring a hole in my pocket. I DONT like getting something new every year..I am NOT jumping on the ARC train. This ARC Ref 6 is so AWESOME that yes to ME it is a jaw dropping difference between the 5se. I have a Krell FPB 600 and B&W Matrix 800s and never ever will sell or upgrade them . Thats the way I FEEL about the ARC 6. And Jim Morrison and Jim Hendrix came back from the dead and he appeared in my room !!!!!
