This support issue is probably the main potential stopper indeed. The person who sells the 39 just got it revised and everything seems to work fine. I know I'd take a risk by buying it. I'm just wondering if the 39 is really as outdated as one could think. I like the analog sound style of the late 90s ML products but what I don't know is if some of the more recent DACs are miles away from the 39 or just different (as in more details, wider soundstage, ...)
