Would be great if I could adjust the bass myself a bit. Some songs are now just a bit too much. Furthermore vocals are missing that spark and sound quite dull. I have the idea that you are boosting the mids which pushes high freqs a bit to the background.

If you click the Icon and then on Sound Engine, you can select from different virtualization engines.

My default engine does a 1.5 gain on <200 Hz. If you don't like that, choose "Hajo's echo-free 5.1 system without bass boost" or one of the "(ear plugs)" NEW AUDIO TECHNOLOGY engines. Those don't apply my Headphone Equalizer.

Actually I also just remembered that I do, in fact, reduce the highs a bit on both "Hajo's" virtualization engines to make them sound closer to my living room stereo system. The "NEW AUDIO TECHNOLOGY / Music" engine should give more highs at the expense of also introducing a bit more room echo.
