I went to that show. I thought the KEF R3 was the best speaker I heard and I also liked the Buchardts. It was a bit hard to tell because they played some wildly different stuff for each speaker even within the same genres. I was also impressed by the Totem Sky. I traveled from Tucson so it was my first time hearing most of these speakers. The Philharmonic Monitor didn't really knock my socks off but it is basically a full range speaker at that price and in these class of speakers (price-wise) it was unique.
At the show they were using Parasound amps to amplify everything. I haven't heard the Hegel so I don't know if there is any sonic issues that would affect one's opinion on that.
