Vincent CD-S7DAC skipping.

I thought i'd post here as a few people have this player (Audiolabyrinth, has owned a few, I believe).

I have been getting intermittent skipping on some discs, mainly towards end of discs. Wipe my discs, brush tray etc. I have 6 other players and don't have a problem when I put the same discs in the other players.

The cause for concern is I set up a Vincent CD-S7 (the same player, without extra DAC & single ended only), Has the same laser mechanism and he has the same issue but skips more frequently.

I took my player into the service centre yesterday, while still under warranty. My concern is that both players have the problem, while it is hopefully fixed under warranty, this maybe an issue with this particular laser mechanism, or whatever else is causing the skipping, and could be costly to keep replacing when out of warranty.
