I've just treated myself to a Cambridge Azur 640C CD player and matching amplifier. It sounds really good but I have noticed that some discs make a fairly loud ticking noise whilst playing. Its mainly CDR'S but it does happen with some original discs. I have my system in a small study and play at relatively low volumes, so it is quite distracting sometimes. I'm new to HiFi so I really don't know if this is normal. Anyone notice this with their drives? Any comments appreciated!
