Johnk, per your comments about the old 2.2 version of the Duos. I never heard that older model, but what you mentioned seems right on. A large portion of the difference between the 3.2 Duos & that old model addressed the very issues you mentioned. The crossover changed, there were subwoofer changes, and the cables and power cords changed. Currently, a new version of the Duos is available which no doubt provides further improvements.
For those who knock the speaker, I respect your opinions. No audio product fits everyones priorities and goals. I do maintain that the objections people made are mostly if not entirely due to artifacts of setup and system matching issues. As with any high performance product, imperfect results readily occur if one but has few listening auditions & if respectful attention is not given to the setup and matching of components. And sometimes it takes living with a product a period of time in order to get the entire system in sync. Just one case in point. If I based my opinion on Quads from but hearing them at shows or at Quad retailers, Id critique them to no end. Yet, when properly set up and matched with synergistic components, we are talking about a legend.
The Avantgardes have the potential to perform in ways that other speakers cannot. Although this performance is not for everyone, it has brought significant pleasures to many users. For many of us, the AGs provide the sonic performance that ends our quest for the last speakers well ever purchase.
Chris, there is something about Avantgardes that caught your attention, and thus it seems worthwhile to audition them. Although you will have to travel a ways to listen to them, they or any other speaker in their class represents a considerable investment. Maybe making said trip a practical thing to do prior to spending the $$$.
