but the service centre did say that the player only needs the firmware update because of the problem with sacd playback issue and normally if there is no issues they do not update them only when there is a problem so what ever software that Yamaha put on theses players from the factory is normally ok but Yamaha release new versions of firmware now and again on the high end CD players only but jo public do not get to do there own firmware updates because sometimes they are not needed so the Yamaha service centres do the firmware when the product comes in with a problem they check the firmware .
That makes sense. If it ain't broke, don't fix it. I downloaded and installed a firmware update for our Yamaha R-N602. But that was an update with extra functionality, not because there was a hardware issue.
The problem with the CD-S2100 seems a very different one. They may want you to come into a service centre to check that the problem can be solved with a firmware update and there is not another problem. It's very annoying when expensive equipment goes wrong. But at least it can be fixed. It still is a waste of time.
