Decision between Zu Definition OR VS DB99

I am adding a third speaker to the above two, the AG Duos. I am getting a fantastic deal on them and they are pretty much the same price of the above two. How would the Duos compare with the Zu's Definition and VSA DB99.
Thanks

The Druid comes much closer to the performance of the Definitions than an educated guess would allow

Interesting. Maybe the smaller *sounds* clean, or "faster"?

The differences, such as they may be, can probably show up easily on orchestral music (classical).

I think Ton1313 could help here:
Trying out a piece that requires a full symphony orch -- just to gauge if the bigger speakers allow one to "see" more of the musicians; it doesn't matter if the upchain system is different.

You guys have got me intrigued by these spkrs:)

To those who have both Druid and Definition, allow me to state the obvious assumption (hopefully true), that any comparisons you make are done in the same room with otherwise identical equipment, etc. As bass response is very much the issue here and it is highly affected by the room, I am sure you have nullified this variable, but just wanted to be sure.

I owned the Druids and upgraded to the Def's. I've compared in the same room with the same equipment. The Def's keep the strengths of the Druids (speed, immediacy, tone) and add deep bass, even more power handling, a more refined top-end, and a bigger soundstage.

But, the Druids are spectacular in their own right. This isn't on-point to the VS vs. Zu so I won't elaborate - just a response to previous question.

I have a question about the Druids. From looking at their pictures they look thin. They look like sound panels. That and from what I read in the past about one cone drivers that combination does not equal a very loud dynamic speaker. Compared to maybe Paradigm v100 or Silverline Sorino or VS-4 JR's. The weakness of one driver to do it all was they could not play loud. From the looks of things I get that impress with these. They seem to me to be very nice speakers. Reading the litiature of their website says that these speakers do play loud. But how loud is that?
