I don't think that thyname was implying that hand claps are sibilant by nature. I think he was implying that the brightness of his room might be contributing to his sss problems. On every speaker demo I have conducred the first thing I do when I get in the room in clad my hands together once. The echo factor tells me much about the liveleness of the room. In the original post of the review I mentioned the Sonus Faber and the Martin Logan demo rooms had so much echo I asked the sales person how he expected to sell speakers costing this much money demoing them is such an acoustic cave. They might as well set them up in the tile bathroom. Excuse if I misunderstood your comment but I think the hand clap is a good start to any audition.
