IMO since you have C1 MKII's I think the 3.4LE's would be closer to your C1's as far as overall SQ. I've heard the C60's at Axpona but not the C20 or C30. I've listened to both the 3.4 and the LE's but not side by side. I would say the LE's are a 1/2 hair more forward in the mids and highs. I have only heard the smaller excites.
That said I did own both the C1 and later the C1 Signature for just over 5 years. IMO the Confidence is the most natural sound in the entire Dyn lineup.
Good Luck
