My experience is limited to the Duo, not the Trio, but the speakers are enormously revealing. I used them the first year with a pair of Audiopax 88's and they were delicious. However, the move to the Lamm ML2 was noticeable in a variety of ways.
The speakers also benefitted from Apex footers, and very good wire- the jumpers that came from the factory pale by comparison to the aftermarket choices.
I have never been completely satisfied with the bass from the Duo though. Maybe it is me, or my room, but the problem isn't lack of bass, it is a discontinuity in the sound between the horns, which are very open, and the monkey coffins, which sound like amplified speakers. Perhaps in a large room- large enough to get the distance you probably need to let the Trios converge properly- the bass can be sorted out. I know AvG now offer a smaller horn-loaded woofer other than their monster bass horn, but I have not heard it. Jim Smith is a very good guy and quite knowledgeable.
