I heard these at Goodwin's outside Boston, driven by ARC tube integrated and sourced by Nagra CD and dynavector/nagra vinyl. They were in a long wall setup in a medium to large room, not too far from the front wall, maybe two feet. I was perhaps two feet from the back wall. This setup worked very well.
I listened to Tony Bennett at Carnegie Hall, Christy Moore Live at the Point, and Patricia Barber Modern Cool. this type of music seemed ideal for the speakers. Their sound was detailed and involving, with really good imaging, but I had the feeling that these would not be happy unless paired with tubes or warm electronics, similar to the original 3's, which I have in my bedroom setup. The 3XLs are bigger, and have somewhat deeper bass.
Very nice speakers, worth a trip to hear them. I was primarily interested in hearing the Magicos, but these exceeded expectations.
