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.

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

Average Technical Grade

D
  • Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.
Bass D
Bass is light and underwhelming. While some faint rumble exists, it lacks punch and authority in any meaningful way.
Mids D
Midrange is significantly uneven with coloration. Some frequencies are boosted while others are missing, creating an unnatural tone.
Treble E+
Treble is noticeably dark and lacking extension. Cymbals lack shimmer and high-frequency details are obscured.
Dynamics D
Noticeably compressed dynamics. Musical expression suffers with weak transients and poor contrast between quiet and loud sections.
Details D
Modest detail presentation with significant loss of texture. Nuances are masked and complex passages become congested.
Imaging D
Modest imaging with basic left/right positioning. Lacks precision for center placement and suffers from positional blurring.
Gaming D-
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
