Yes, I went to both Fern & Roby rooms. Went to both without paying attention to what other gear was in the rooms, so I just listened with an open mind. Visited the room with the Spatial speakers first -- just lovely. Open sounding, smooth/liquid, and musical. My first thought was "hey, these Fern & Roby folks have got something here"....not realizing it was the Spatials providing most/all the goodness. Next went into the other F&R room with F&R speakers. It was.....just OK, didn't hold a candle (or even a lit match) to the Spatials.
So, in short, the Spatials were special. Well worth an audition. I could have sat in that room listening for a good long time. Only a few rooms at AXPONA made me feel this way, this was one of them.
