This could be colouration or the truth, hard to say without listening to a wider variety of recordings than we did. If you have too much colouration some recordings are enhanced, some become unlistenable. That's when you've gone wrong. If you can get it sounding how you want it without falling into that trap, you've cracked it.
I've not cracked it yet.
