Mad, I liked that the 7's disappeared better than just about any speaker I've ever heard including the 3's. The fact that they could be tuned to fit the room exactly that they were using them in with pitch perfect bass was also a huge plus.
The 3's might have an advantage in reproducing the scale and overtones of a full orchestra while the 7's seemed uncanny with small groups and voice. I tell you, I'd love to have the 7's over for an extended visit but couldn't comment in useful detail until I had.
No question though that they are in a small class of the best speakers I've heard outside my home.
