The fragility of SACD players, perhaps

Addendum to the last post, last night the Marantz started skipping and stopping on the wonderful sounding SACD anniversary issue of Dark Side of the Moon. Ouch....all my ranting about cds might be misplaced (though I still think they are badly packaged!) as it now seems likely the Marantz could be the cause. I located an SACD owners and lovers forum, SA-CD Net which contained a several years old thread outlining problems others have had with their SACDs. Seems it's common enough for players to fail on the SACD layer while reading the red book track just fine. A series of not-terribly helpful back and forths with the Marantz customer contact line has me now packing up the SA11 for shipment to the nearest service center for a check up and hopefully, warranty-covered correction. We'll see.
