My advice is to contact the dealer and/or Mood. I’m sure they will be able to address the issue.
One of Norah Jones’ CD has copy protection that adds gap normal CD players can handle because of how they error correct. Computers, however, can’t rip it easily.
I wonder if that’s what you’re hearing.
I have just checked and you are right, it is written “copy controller” with a logo in the back of the sleeve. You think this is the issue ? So each time there is a protection i will hear this ?
Maybe. I was just sharing that fact, but best to check with Moon.
I am waiting their answer and provided them this new information.
If this is it, I will keep it as it is a wonderful sounding unit. If it is something else, I will keep asking for refund
When I come across CD’s like that, I take great satisfaction in ripping them and placing the disc into storage. 
Hi,
I own the same unit; I’ve had no issues with it so far.
I had one Dianna Krall CD that would cause the 260 to skip around the tracks. I removed the brand new CD and washed it, using warm water and a tiny bit of mild soap, then of course rinsing thoroughly.
That took care of the issue, the CD plays fine now.
Your issue is very different; I wonder, as your unit warms-up slighty, could it be an internal connection or a solder joint that is intermittent?
