Hi kucharsk7
I'll have a chance to listen to the Botticelli soon. It's a dream speaker for sure. Several feedback/reviews of the speaker mentioned bass similar to cone bass with all the slam missing in other planar speakers.
As far as Carver's new ALS speaker is concerned, they require careful setup. I have not heard them sound good in any of the shows.
It took me 6 months to have them sound great. Once set up correctly, I can think of any speaker near its price coming close to the majestic sound stage, imaging, extension, delicacy and dynamics. May be the new Magnepan 30.7 can compete, but I doubt it will have true 20 Hz extension with the slam and power in the bass.
