Sorry can't be of immediate help, however I will be picking up my SC-05 last week of March along with the delivery of my new Axiom on-walls (W22's & W150). I will let you know how it goes. I chose the SC-05 because I liked the idea of the ICE amplification, the home media gallery (I put all media files on my NAS) and a well rated on screen GUI as well as good professional reviews. Won't be able to help with M80's specific feedback obviously. Feel free to prompt me with a PM come the end of March!
