See Maestro SE but with worse bass.

The FATFreq Grand Maestro offers a highly adaptable sound signature through its NOAH modules and vocal switches, enabling four distinct tuning profiles. The black NOAH module emphasizes sub-bass "slam," while the blue variant provides tighter "rumble" control; combined with the vocal switch, these allow shifts from a bass-forward signature to a more mid-centric presentation. Bass is deep and authoritative but avoids midrange bleed, while the treble—handled by electrostatic drivers—delivers clarity without sibilance or fatigue.
Technically, it excels in imaging precision and creates an immersive, three-dimensional soundstage that positions instruments with remarkable specificity. However, its large shell size may challenge those with smaller ears, and it demands power-hungry sources—often requiring high-gain amplification to reach full potential. The deluxe package includes both NOAH modules and an upgraded cable, enhancing its tuning flexibility.
