I made a point of hearing the Alyssa's at AXPONA this year. I visited the room twice and unfortunately the demo music was always focused on their amazing bass reproduction, to a fault I thought. I would have liked to hear something a bit more balanced to see how they perform across the spectrum. Not knocking them by any means, but it does seem like a speaker that you want to hear before you buy it.
Noting the previous post, I also visit a room with the Triangles, it was really good, and yes lively.
