Just to add my two cents.
I have a 3 way Gallo Nucleus Micro system, with some really junky surrounds. I have been planning on replacing the surrounds with another pair of Micros forever. Last January I had a chance to visit a dealer in Dallas, TX, where I listened to his Micros, and compared them to the Micro Ti's and the A'diva Ti's.
I really like my Micros, but they do have a bit of a mid-range excess to them. The Micro Ti's did not have that mid-range hump, but to my ear, and with the dealer's equipment (a Denon receiver, sorry don't remember the model), they had a rather harsh high end. All in all I thought the original Micro still sounded better.
The A'diva Ti, which I normally wouldn't have considered, and just plugged in on a whim sounded fantastic. It did not have the mid-range coloration of the Nucleus Micro, and while it definitely had more high-end output, it was very smooth sounding, not at all harsh like the Micro Ti's.
Now instead of scrimping and saving to get two more Nucleus Micros for surrounds, I'm scrimping and saving to get two A'diva Ti's for the front set, and send those Micros to the rear positions.
I also got to play a bit with the Reference 3.1s during that visit. Wow!
I saw two people walk out of the store that day with a set of them. Everyone who listened to them where blown away.
