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.
Mids C+
Decent midrange performance - balanced but unremarkable. Adequate clarity for most genres without notable flaws.
Treble C-
Average treble performance - present but lacking refinement. Some graininess or splashiness affects clarity.
Dynamics E+
Limited dynamic range with poor micro-detail. Subtle volume changes are lost, and transients lack proper attack.
Soundstage B
Good soundstage with proper width and depth. Instruments have clear positioning with reasonable front/back placement.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

Average Technical & Tuning Grades

Average Tunign Grade

E
  • Tonally jarring or fatiguing. Frequency clashes (e.g., piercing treble, bloated bass) make extended listening unpleasant. Poor genre adaptation.

Average Technical Grade

E-
  • Noticeably blurred or congested. Struggles with basic instrument separation; details are lost in simple tracks. Feels "flat" and one-dimensional.
Mids D
Midrange is significantly uneven with coloration. Some frequencies are boosted while others are missing, creating an unnatural tone.
Treble E-
Treble is extremely rolled off and veiled. High frequencies are barely perceptible with significant loss of detail.
Dynamics E-
Extremely poor dynamic expression. Lacks any sense of impact or volume gradation, making music feel one-dimensional.
Soundstage E+
Limited spatial presentation with minimal width. Instruments lack separation and sound clumped together with no depth.
Gaming E-
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
