Well, I just did search on TL082 and it looks like it's a "general purpose" opamp. I guess replacing those with a widely "audio-approved" opamp such as LM4562 (I love them, I don't see the point going BurrBrown) could bring very interesting results.

The TL082 is nasty in comparison to modern op amps. Getting rid of them should make the improvements you desire. If the circuit impedances are > 5K ohms, the OPA2134 could be a better (less noisy) choice. Decoupling per the datasheet is not optional. And most of all, have fun!
Dark energy? Ridiculous!

I don't have the board under my eyes right now, and i don't have any schematics, but i guess each opamp has two 10uF lytics about 1,5inch distance from it, and a couple small value ceramic (?) caps, so it looks like opamp decoupling would be enough for OPA2134?...
If there are small ceramics on the power supply pins very close to the op amps, you should be good to go. In all my travels, I have never seen vintage gear so equipped but it is possible.
