I've been using a pair of Omega Hemptones since 2005. When I first hooked them up, the sound was disappointing - - a bit thin and "papery". Louis Chochos had told me that they needed to be broken in for about 100 hours before they would sound really good.
As I recall, during break-in Louis advised positioning the speakers so that the drivers faced each other and playing them at a moderately loud level. I did as he advised (breaking the speakers in 9 or 10 hours at a time while I was away at my job), and gradually the sound did improve. They really bloomed after roughly 200 hours, and I absolutely love them.
