I really think we should try and keep this thread constructive, and not start any bashing and name-calling even before the full experiences of the participants have been reported in. As to what has emerged so far, I think it's actually a bit promising - I think all sides in this "AVI war" have been proved right to a certain point. According to Lindsay's post in another forum (which is run by a guy some people apparently see as evil), all the participants agreed both on which system sounded the worst (the ATCs), and which sounded the best (the Sentrys). It's not clear yet how much better the participants thought that the Sentrys were compared with the AVIs. I guess there might have been differences of opinion as to the magnitude of the differences.
On the one hand, this proves the point that AVI owners often have made: That an AVI system can sound much better than very expensive traditional systems, consisting an amplifier and passive speakers. Both the ATCs and the Hegel 300, mind you, are highly regarded. And yet, there seems to be complete agreement among the participants that the AVIs sounded much better than the ATC/Hegel system. This agreement seems to include Lindsay as well, who I think has been critical of AVI in the past (sorry if I'm wrong about this, Lindsay). In this sense AVI's claim has been vindicated, I think: If one wants to have really really good sound, going the AVI route might be one of the easiest and cheapest.
On the other hand, if the Sentrys were indeed preferred by all the participants, it shows that some of the most hyperbolic claims made by AVI and by some AVI owners are exaggerated. The Sentrys are passive, methinks. Still, there seems to be some agreement that they sounded better than the AVIs. This means that passive speakers can indeed outperform active speakers. There may be different reasons as for why the participants preferred the Sentrys. My guess is that it may be down to the size of the woofer, partly, and the tweeter is hornloaded (I'm a huge fan of horns, if it's done well).
I'm still looking forward to reading more about the results. But based on what has leaked out, I think this should serve as food for thought for people on both sides. The active crowd (including me) may be advised to show some more humility with regards to the merits of certain passive speakers. The passive crowd may be advised to acknowledge that active speakers very often will provide superior value for money, and may outperform many passive speakers in the same price range.
That's what I take away from this so far, at least. All in all, I think this is a positive thing.
