Possible issues with Marantz CD player

I have a Marantz CD player,  CD 6004.  Lately, I  hear  a loud  burst of  static when playing CDs. It is random, and intermittent rather than a constant buzz.  Quite pronounced. Not a hum or buzz from light dimmers or TV or the like. 
Sounds more like a skip in the CD,or like the sound a tuner would make if you were changing stations and lost the signal.  A loud squawk.  

I have tried, but so far cannot replicate it with vinyl.

It has occurred with three different CD, usually on the first song. Then it will usually play the rest without incident.

Possibly some problem with the laser?

We have two large, active German Shepherds, so I thought we might have had a tail-strike to one of the speakers.  I took the dust cover off the speaker, examined the woofer visually for tears or deterioration.
These are Klipsch Heresy IIs, so the tweeter and mid range are pretty well protected.  It looked OK, and if it were the the speaker, I'd expect to be able to replicate the issue with vinyl. 

I also checked the speaker connections, at the speaker, and at the amp. Seemed solid. 

CD player is maybe 5 years old or so, pretty much bulletproof until this, assuming it  actually is  a problem the CD player. 

Anyone had a similar issue with CD players?  Or picking up random noise in the system somewhere else?
