CCA CSN Scorings

Average Technical & Tuning Grades

Average Tunign Grade

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

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 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 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.

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+
  • Competent but unremarkable. Decent detail retrieval in quieter tracks, though busy sections challenge cohesion. Imaging is average, lacking depth.
Bass B-
Average bass performance - present but unremarkable. Has reasonable texture but lacks depth and physicality.
Mids A-
Excellent midrange with natural timbre and great detail retrieval. Vocals are forward and emotive with lifelike instrument reproduction.
Treble C+
Decent treble with acceptable extension and detail. Can sound slightly unrefined but avoids being harsh or sibilant.
Dynamics C-
Average dynamics - passable but unexciting. Transients are rounded and micro-dynamics lack refinement.
Details C+
Decent detail retrieval. Handles most textures adequately though micro-details and ambient cues could be more pronounced.
Imaging C+
Decent positional accuracy. Good left/right placement with acceptable center image, though depth positioning is approximate.
Gaming C+
Fundamental left/right positioning with limited depth perception. Works for non-competitive gaming but lacks precision.

A little sharp in the tuning, but decent overall. Respectable value for $20.
