I’ve got a few variables to consider here though. For one I already have an NDX and an ND5 xs and in this country they are exceedingly difficult to move on, at least for an acceptable return. In which case I now have an opportunity to “get rid” of them both and get an NDX2 from a dealer at a reasonable price. The 252 is considered only because it’s reachable as used as of right now. But I don’t want to be excessive and put loads of funds into the system at once. Which it, in my mind, would be to purchase both a “new” source and 252. It seems as if concensus (almost) here on the forum, so far, is source first, which I can relate to and appreciate. I also manage to interpret, from several discussions here, that the NAC and NAP seem to need some sort of equality of quality so to speak. Therefore a NAC202 with a NAP250 ads up to a somewhat unbalanced system. While a 282/250 or 252/300 makes more of a balanced system, all according to the forum. I would have thought a 252 would work fine with a 200DR and hoped for it too, of course. Finally the source needs to be up to the task, otherwise shortcomings might be exposed by the ever rising transparency of moving up in the hierarchy of nacs and naps. I suppose my speakers are up for going all the way to the 500-series, but that´s a whole other ball game.
So to summarize thus far, First upgrade source, either to NDS or to 555PS powering NDX. Or ad XPS DR to NDX. NDS + 555PS is as much as a new NDX2 which also is an alternative. After that, what ever it becomes, upgrade the NAC, either to 282 or 252.
When quoting costs I´m referring to the used market here in Sweden except for the new NDX2.
