Re sounds. Full-bodied, rich but detailed as well. Big sound stage. Bass is not overbearing even though it has big bass drivers. I drive them with a Lux 509x. Your Michi unit has more power. I'm sure the big Dyns would kick butt with your gear. I was able to compare them to Focal Sopra 2s, and I preferred the Dyn sound. Others may differ. I like the soft dome tweeter. Non fatiguing! I'm sure the SF will be stellar too as would Revels. I haven't heard them so I cannot comment. I might also mention that I got to hear a set of Confidence 30s. Those were terrific as well, but I thought the 60i more than held their own.
