Micke,
I agree with both of the previous posts:
--Drop the cathode follower at the input. There are a number of reasons to use a follower, but for the life of me I can't think of one to justify the use of one as an input buffer. One at the output is fine. (Incidentally, I'd consider raising the 100k at the output to 1M--it's there to drain DC off the back end of the coupling cap at turn-on, which is fine, but it will also be in parallel with the Zin of the amp/crossover and constitutes an unnecessary load.)
--Omit the cap for the cathode. The gain will drop when you do so, but you'll not only avoid an electrolytic, you'll pick up a bit of local degeneration (aka feedback) which will reduce distortion. These days, you don't really need a lot of gain in a preamp.
