Ndeslions,
To answer your question, none of the speakers you mention will significantly outperform the Ravens in the areas you are looking to improve. You will loose the bass slam, dynamics, clarity and depth you have now. Those speakers are very good and may only offer you a different mid-range presentation.
To get a bigger soundstage, you need to move the Ravens off of the back wall about 2-3 more feet into the room. Your placement from your listening chair should be looking down the inside surface of the Ravens and only seeing 1/8" - 1/4" of the front side to the back side pannel. That will give you the best soundstage.
Next you need to address you AC with filters and dedicated lines. Filtering your AC will give you a huge soundstage left to right and improve upon the depth also. A few caps on my deddicated line were the biggest improvement that I have ever tried in my system and a few others. Take a look at this thread.

Last depending on the model year of yoru Ravens, Mike has another cross-over upgraded that he will do for free. Big improvement over the last ones.
Email me if you need more info.
Happy Listening.
