Thanks for the advice, Loomisjohnson. I bought two pairs of mint KEF Reference 102s, and have replaced the KEF 200C with one of the speakers. The 102 is indeed a better match with the 104.2s. The soundstage in 5.1 is now seamless, whereas music seemed uneven across the soundstage with the 200C. I plan to use the other 102s as surrounds.
