Harbeth has a nearly 90 lineage in making speakers, starting with the BBC. The Harbeth form was designed by engineers back in the 1960s and the high end studio monitor was born. IF you hear the Harbeth's you will understand. However, no matter the driver construction, the crossover, and the cabinet, the speakers are still flawed. This is especially true of the LS3/5a. However, older audiophiles love them even with their flaws. There is something about these speakers. They were designed in the non digital analog age and produce the original "organic" sound. Personally, I would not buy them There are so many more speakers for the money which outclasses them, but there is a strong market, especially in Europe.
