When i had my Meridian CD player system (500 transport, 566 DAC, 518 DSP) i would occasionally get the ticks and pops you are describing. I had to power everything down, wait a couple of minutes, then power up again and the problem was gone. If this doesn't work for you, or it keeps happening frequently, call your Meridian dealer or service person to make sure your upgrade is functioning properly.
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
