I have owned the JC-1s (not finicky at all) and now use the Krell FPB 650M monoblocks. The Krells are a little darker sounding overall than the JC-1s. Maybe a little more high freq. detail with the JC-1s. But the Krells are smoother and more musical. As powerful and dynamic as the JC-1s are they cannot compete with the Krells. Both are good amps and I could live with either, but I prefer the Krells with my Thiels.
