I've heard the ticks that you're talking about. They occur at consistent points in the music and Aural Illuminator doesn't fix them. They might be static in the recording process. In the early days of cd, "Frankie Goes to Hollywood" catalogued the ticks on their cd and gave likely causes.
On the bright side, even my worst cd has few ticks than my best vinyl.
