By KEF 104 I assume you do not mean the Reference 104/2s. I have a pair of Reference 104/2s and four Reference 102/2s. The Reference 102/2s are very fine speakers, but IMO the Reference 104/2s are better. I run all bi-wired; the 104/2s are crossed to a Velodyne HGS-15 below 80 Hz. I've yet to hear a speaker that induces me to write a check to replace the 104/2s, even the lovely Sophias which would be my choice should a 104/2 fail.
