I've been doing more playing/testing than listening. I wasn't as enthusiastic as some of the new 15H owners when I first got it, but I finally have them both dialed in nicely. I've done listening tests as well as graphed the response and the 3.3 definitely adds. The response is flatter and it fills the room a lot nicer with both.
I can see myself picking up a second 15H eventually, and even then I doubt I'd get rid of the 3.3. If you're looking to upgrade, I'd recommend adding not replacing. Multiple subs are king. I don't think you can lose with another 3.3 or 15H.
