I switched from a Windows laptop to a Macbook Pro earlier in the year, mainly (but don't tell work) for a better performance from iTunes. However playback is actually far worse through headphones or the speakers due to pops/clicks/stutters in playback. I don't seem to have the problem when streaming to an Airport Express or Apple TV though... I was working (it occasionally happens) using the Macbook earlier today and every track that played either popped, clicked or stuttered for a fraction of a second. It's very noticeable after a while and completely ruined the listening experience. I never had this problem on my old windows laptop, even though it ran far slower and had other problems. I've tried searching the web but have struggled to come up with much in way of a fix. Please help!
