I had the C60s for 2 years and went through absolute hell.
First it was the 400 hours of break in needed to make them sound bearable and then the disappointment of a cold, compressed sound, totally stoned timbre, and confused, out of focus soundstage. I paid half the list price for them and went to an immense effort to get rid of them at 3000 euros. I had them on sale for a whole year at 3000 euros, people came, listened, and left. Good luck.
