You have at least as much experience with this as I do but as I listen and compare the clean youtube version to the parked file, the first thing that strikes me is ill-advised eq, giving it a dark distant sound. The second thing is likely the artifacts of either poorly adjusted or poor quality noise reduction; the reason the trumpets are less affected is that with any noise reduction program artifacts are most noticeable on lower level signals - signals which are closer in level to the noise which is being removed.
That's my two cents worth!
