I just got the D5000s in. I already have the D2000s. I read all the comments about how these are a significant step up from the D2000s but took that with a grain of salt. After going through a marathon listening session last night with all my favorite material, I didn't get to sleep until 2 AM!!! Holy moly the difference is, pardon the pun, ear opening!
I can't imagine stepping from D5000 to the D7000, which apparently is less of a dramatic difference, than going from D2000s to D5000s.
Anyone interested in a pair of D2000s?
