I have a Marantz amplifier (PM7200) and CD player (CD5003), with Kef Concerto speakers. There is a persistent crackling noise, not all the time but usually several times in any CD, sounding very much like the static noises that you sometimes get with a vinyl record. I think - though I can't be sure - that while it's happening the actual audio sound is also degraded.
As far as I can tell it's random, i.e. it doesn't always happen at the same point on a CD.
It never appears when I'm listening through headphones. But when the headphones are in use, it can still be heard by anyone listening to the speakers.
There is quite a long cable run to the speakers, and the cable is not "special" - it is however quite heavy copper cable. I have made and re-made the connections at both ends.
I don't want to restart the debate about whether cable can make subtle differences to the audio sound. I'm talking about a gross and very obvious noise. Does anyone know whether the cable itself could induce this kind of thing?
