Average Technical & Tuning Grades

Average Tunign Grade

C-
  • Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.

Average Technical Grade

C
  • Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.
Bass C
Subdued bass response that stays mostly in the background. Lacks energy and impact but maintains basic definition.
Mids C-
Midrange is passable but unrefined. Lacks detail and smoothness, with occasional harshness in upper mids.
Treble D+
Uneven treble response with noticeable peaks and dips. Can sound both dull and occasionally harsh simultaneously.
Dynamics C-
Average dynamics - passable but unexciting. Transients are rounded and micro-dynamics lack refinement.
Soundstage C+
Decent spatial presentation with noticeable width. Some depth perception but height dimension remains underdeveloped.
Details C-
Average resolution - reveals basic elements but misses subtleties. Satisfactory for casual listening but lacks refinement.
Imaging C-
Average imaging - reasonable localization but lacks specificity. Instruments have general positions but lack pinpoint accuracy.
Gaming C
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical. Value-to-cost may not be optimal for gaming-focused users.

The defacto basshead rec before the more expensive stuff. Super fun sub-bass, textured, heavy, prolonged decay for more reverb in the bass, well-balanced as well, smooth and scales great. Tech is not its strong point, and DON'T buy from FatFreq directly!!!
