Thanks fot the reply, and you're forgiven for having started listening to CD's in the 70's

So you reckon there has eventually been skips and a few seconds drop at the end on one disc...
I've made some statistics and it seems that the people in the US/Canada didn't mention issues other than gapless problems.
Whereas most of the EU units have some skips, drops, on top of gapless issues with V 2.1 at least...
This is a guess but most probably these (mainly black, not the earliest silver versions) first batches, were different from one region to another, and the EU ones show more issues than the US/CA ones.
Let's see if theses issues persist with later upgrades, V22 seemed to focus on gapless problem...
