It was great to be able to hear the LS50's at Mapman's place. I was most surprised by how poor they did in a large space; even with a fairly powerful amp and the Dynaudios clearly sounded better in every respect. I always suspected that the LS50's performance in my smaller room was being limited by the size of that room, but now I'm not so sure. As soon as we moved the speakers out of his larger room and into something more my size, the performance improved. Besides really enjoying the Ohms that I heard, I also gained a newfound respect for Dynaudios which I'd never heard before either. Nice sounds!
