I don't think they where meant to be compared to each other. I think the RF7 was just discontinued due to lack of sales and the fact most be people like smaller towers. Not that it was a bad speaker. It was a great speaker. Just didn't sell that well.

PSB, Paradigm, Energy, and B&W are some others to look at. Go with what your ear likes and make sure the place you buy from has a liberal return policy. Some speakers won't sound the same once you get them home due to the acoustical changes in the rooms.
