Some CD's do have clicks and pops as part of the music, intentionally done for more of the analog feel. Make sure it is not the track you're listening to that is to blame, in which case, the noise likely won't do any harm to your speakers....
How to handle Clicks and pops
I recently upgraded my Meridian 508.20 to 24 bit (Bow Wazoo integrated amplifier and Sonus Faber Grand Piano Speakers). Sometimes when listening to music, I get clicks or pops in the music (both left and right speakers). It does not happen all the time but I do not like it. What does this mean and what can I do to fix it? Could the problem be with the Meridian 24 upgrade? Could the problem be with the amplifier, speakers or CD's? Thanks
