"bring a certain roughness to the treble, some kind of "dirtyness" that's very obvious on compression drivers."
"the opamps are TL082"
Probably the source of your problem, as long as there are no series electrolytics (if there are, bypass them with 0.1µF film types).
There may be a DC off-set problem switching from FET input opamps to bipolar.
OPA2134, 2604 (FET types)always sounded good to me.
