One of the biggest upgrades I've done was when I went from an Adcom solid state GTP preamp (450?) to a quicksliver linestage with my NAD 214. The jump in performance was huge. I'm not familiar with the NAD 1000 but I wouldn't be surprised if you got the same gains I got.
After the Quicksilver, I went through several more expensive power amps before I found one that was much better than the 214. That there is a pretty good amp.
