I love how dealers talk their book. I love that many have never heard the equipment that they disparage. I did not suggest that anyone look at a Gallo Due (learn what the equipment is named before you talk smack about it, think a DEALER would know that), in this price range. It also is amazing that The Absolute Sound's reference surround system is a total Magnepan system. But Cinematic Systems knows that dipoles are terrible for theater, so much for trade publications and all that knowledge the Editorial staff there has. They should have known to call the Niles Audio dealer from Pig's Knuckle Arkansas before they put that system together.
In your price range Maggies, Innersounds or Vandersteens would be great systems. Cinema SLAM comes from the subwoofers, in general, and all of those are augmented by such. A Maggies system would need multiple subs, maybe a Vandy 2wq up front and a dedicated LFE sub for soundtrack. A Sunfire True Sig would do the trick, there are a lot of very good "Boomers". If you want just one, a Velodyne DD18 would compress the whole room and integrate very well for music.
Once again, before you listen to some guy who claims to be some type of audio dealer, read some opinions of other users and trade pubs. You already have an excellent set up it appears, and there is so much good equipment out there that for $30k you will be very happy. Just stay away from Charlatan "Dealers". I guess if you worked at Radio Shack for a couple of weeks in 1978 you can call yourself a dealer.
