Although my own system is 2 channel Meridian digital based (808 + DSP 7200s), I found this forum as I was (and still am) looking for information on the bi-amp crossover for a pair of KEF 104/2s that I am trying to restore for my best friend. We both love classical music, especially opera in his case. I found the 104/2s at a garage sale, and there is a crossover issue that I will start a thread on after finding so much useful information on here already. Looking forward to meeting other music fans. My name is Jon and my handle refers to my odd way of looking at medical care.
