I would not replace a piece of gear with its manufacturer's next iteration of the same piece. I haven't heard the 372, so I could be completely off here, but I'm guessing the sonic differences are not huge. Sure, NAD says there are some, & no doubt there are, but remember that they are justifying the product update, a process companies are forced into by market demands. Consider: if you were buying a new component, would you buy the one that's been on the market for 5 years unchanged, or one that's been out for a year or less? Which do you think would have the most sophisticated technology? Which do you think would give the most bang for the buck? Most consumers will go with the newer option.
Bottom line is, obviously, that you should listen and then decide. Realistically, however, most of can't listen to a very wide range of gear, and most of us can't even directly compare our gear to the stuff we do have access to. On that note, hopefully someone who has heard both amps will have some real rather than hypothetical advice.
