Well, there is some CD copy protection that introduces "bad bits" into the music. It decreases the quality, but CD-Roms apparently can't read it. CD Clone, in my opinion, will still copy it though. Ripping would have to be done from an adjacent CD player, and therefore at 1x speed.
The best way, as always, is to produce good music, where most songs on an album are enjoyable, since it is often difficult to find all songs of an album on the internet. Without distribution on the Internet, the damage is not huge to begin with.
Performers who just have one "hit" song or two per CD will always have difficulties with piracy.
