My most recent were Exemplar Audio's Exception IC's. They are a great bang for the buck! However, the Reveals are on a different level. I have used many brands over the years but the CT1E and the Reveals are the best I have used.
I describe the Reveals by saying they place you closer to the live event. Revealing but organic. Music just flows and you get more of it. The soundstage is wide, deep and although you get excellent instrument location they retain their musicality. I can only imagine what the higher level models sound like.
