DSpeaker has a few options to control things in the digital realm. There is the Anti-Mode 2.0, and the more sophisticated (and expensive) X4. I've used both for years at a time, and found them both helpful They each have a "Tilt" control, not unlike the old Quad preamp, that allows you to quickly dial the treble down, or the bass, or both. For some recordings, it was just what the doctor ordered. And they do wonders for the bass in most rooms.
If you want to keep it analog, I'd experiment with the fanciest Loki. Schiit gives you two weeks to try it out. By then, you'll know...
