I am voicing a system/room with the first US client's pair soon. Should be very interesting.
His area may be slightly larger, but only because it is a sort-of 'T' shape. Actual listening area may in fact be slightly smaller - will have to see what set-up works best in the room.
I heard the G1 and G2 yesterday at Vivid's facilities in the UK and was very impressed, despite the use of AVM amps which I hated in Munich. Home demo with Vitus and Berning on the cards I think.
