I have owned my Audiomeca Mephisto II.X for almost 4 years now, my unit was on only 4 months old when I got it. So far I have never had any problems with it. Sound is superb, most analogue sounding player I have ever heard and I have heard things I never knew were even on the disk. My son also has the same model but his unit is a bit older, he had one issue with it skipping a while back, we contacted Pierre in France and he responded immediately and told us a few things to try. Unfortunately none worked and we ended up taking his unit into Echo Audio here in Portland where their master tech, said not problem we can fix it. And it wasn't, they fixed the problem and his unit is once again trouble free, that was over a year ago. So you can get them fixed should they break but you need to know where to look. So if you want superb sound I would try to find one in great shape. I have heard the BAT and it too is good but the Audiomeca really give you an emotional attachment. The other player I use is a Lector 7T, which is very close to the Audiomeca and after rolling some nos tubes, its one great player.
Good Luck
