It's ongoing, but, at least for the music I was listening to last session (another coming up now) I'm fairly happy with the result with just EQ, and, as I'm listening from a PC, EQ is easy. Hmmm... Easy to put there, at least, harder to learn.
(The thing I have to fight is the tendency to want to make the curve look right, rather than simply listen to the results. Damned brain! The other thing is that my HF hearing loss is sufficient that I now no longer know what "flat" is. Something that I can enjoy is the best I can do. OK, so, in a way it doesn't matter, but in a way it does: I always rather liked the old-fashioned definition of hifi, reproducing the recording accurately.)
