I actually had an extra D250 Pro on hand when my D1000 returned from its CI upgrade. Based on side-by-side comparisons of the D250Pro against the D250CI, it was clear that the upgrade was worthwhile. The sound was more open, with more resolution. This was evident within the first 10 minutes of listening. But what was most interesting to me was that the improvement from adding the second unit to go to the full D1000CI was considerably less than the difference going from the D250Pro to the D250CI. I suspect the very best bang-for-the-buck upgrade solution is finding a cheap, used d-Premier, upgrading it to the current D250CI, and leaving it at that! (That said, I'm still keeping my D1000CI.)
