This is interesting...I was confirmed by KEF techs that there were a few different versions of
crossover used on the early 104/ 2 speakers. But the Xovers were fundamentally the same from a response, the difference being size and shape. Are your newer versions the biwire versions ? My 104/2 share the same behavior as your "new" ones: " The newer one has faster bass, much more detail, clarity and immediacy (I know these are not technical audiophile terms, but my subjective impression.) On the other hand, it also is too bright and hard on badly recorded material, female voice, symbals and some horns." Need to check what are the numbers. I don't know your system, but I believe KEFs like watts. I like my tube amp: VTL 75.
