Charles, the digital to analog conversion process has no mechanism by which it could magically(even if the seller labeled a DAC "Magic" or "Majik")bring out previously unheard or almost inaudible material. That can happen when the loudness level is higher.

You'll undoubtedly enjoy your music through the M100s, and it's probably right that the DSP correction of the speaker(not the preceding electronics)which is at best extremely subtle, wouldn't be a wise purchase.

Enjoy the music, not the equipment.
