Very generally speaking, placed way, away from walls, as you can see in the pictures, the speakers seemed to completely disappear... room almost disappeared... Great sub integration with the speaker and the room. Speaker seemed seamless from the top, down to the subs.
Sonic signature is one of dynamic ease. There is an open and clear sound, like an electrostatic or an MBL. Heck, it's the sound of the Absolute Sound because Harry Pearson said so.
Not sure what the amps were, but I liked the tonal balance: not too lean and not too rich. Overall, sounded as good as I have ever heard it.
Obviously Mobiusman disagrees, so take it with a grain of salt.
