I'd love to able to help, but all those speakers are out my grasp right now..lol.
I have been checking out the Studio 20's quite extensively as of late and really like them, just not sure there are worht $800 CDN. My brother in-law is a big Monitor Audio guy, they do sound terrific! The Silver line he had were the clearest, most open soundstage speaker I had heard at the time. Until he upgraded to the floor standing golds, powered by a Conrad Johson and Denon 5800...

WOW, it's like front seats at a concert and better then most theatres for movies.
Sound, to me anyway, just seems a little less forced and more natural from the Monitor Audios then the Paradigms. My $.02.
