I had a stage 1 (memory failing but did it go 1>2>3 with the series later being replaced by 4>5>6?).
It's a long time ago but I remember being happy with it (I moved from a Marantz cd63 II) and as I said in my previous post it's still going, so I guess that is a positive for the reliability of that generation of Micromega players.
If I was considering buying a player of that age now, I think I'd be contacting Micromega just to understand what the service situation would be in the future (would they touch it, are the transports still available etc).
