Youtube Video Summary
FATFreq Grand Maestro aims squarely at a refined, sub-boosted tuning rather than a crude bass cannon. The bass quality shows real pedigree—excellent control, quick decay, and that clean, floor-shaking sub-bass rumble without smearing the mids. Treble reaches higher with better extension than typical basshead fare, and overall resolution, separation, and balance feel “endgame” in polish. For listeners who want muscular low-end that still plays nice with vocals and air, this tuning reads as a mature, high-performance take on “bass + hi-fi.”
But for pure basshead cravings, Grand Maestro doesn’t go overboard—it’s a bassy set, not a “basshead or bust” one. Compared with FATFreq’s own Scarlet Mini (or Maestro Mini), it brings less sheer quantity and “skull-rattle,” trading slam for finesse; next to ultra-dark hammers like HBB Hades, it’s far more balanced and controlled. The catch is diminishing returns: while the Grand Maestro is the most refined and technically capable among these bass-tilted options, those chasing maximum pound-for-pound slam may find better value in the Minis, and those wanting reckless low-end excess will still gravitate to sets like Hades. For most non-basshead audiophiles, though, Grand Maestro’s blend of sub-bass authority and top-end refinement hits the sweet spot.

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.

Youtube Video Summary
Canpur’s CP74E steps in as the “just-under-flagship” sibling to the CP622B, packing 7 balanced armatures + 4 EST (11 drivers) and a neutral-warm tuning. The graph shows a tidy ~10 dB box from 20 Hz–20 kHz with no wild spikes, and the presentation reads vocal-centric: clear, natural mids without bloated mid-bass or shouty ear-gain. Sub-bass doesn’t hit with the same bone-conducted heft as the 622B, yet the low end is clean and modern for a BA stack, making it hard to distinguish from a dynamic driver on many tracks.
Instrument timbre is a highlight: four- and five-string bass lines showcase lifelike plucks, releases, and string ring; kick drum authority sits in a similar energy window to 64 Audio’s U12t—not a bass cannon, but solid, warm drive. Treble looks slightly more extended past 8 kHz on paper, though in practice the upper harmonics don’t come across as notably brighter. The real gap with the 622B isn’t up top—it’s the 50–500 Hz region, where the flagship’s BCD magic brings extra life, reverb, and decay; the CP74E stays more polite and traditional, albeit with high-quality resolution.
Positioned around $2,700, the CP74E competes strongly with peers and earns a confident “would buy” verdict. It’s the set to choose when the 622B is out of reach but the goal is excellent vocals, realistic instrument texture, and a warm, refined balance. Not the throne usurper—that stays with the 622B—but a serious contender that should fare well against heavy hitters like Grand Maestro and Storm in broader comparisons.
