Comment: A sidegrade from Wan Er, but a more correct sounding Chu. Well tuned like the Chu, without the metallic treble B-grade bass, general technicalities

Average Technical & Tuning Grades

Average Tunign Grade

C
  • Uneven emphasis across the spectrum keeps the presentation unsettled and awkward. Acoustic instruments lose their natural body.

Average Technical Grade

E+
  • The presentation is claustrophobic and blurred, leaving simple arrangements sounding chaotic and lifeless. The presentation feels more like background noise than music.
Mids C-
It delivers a workable midrange that could benefit from smoother transitions. Timbre isn't quite convincing yet.
Treble E+
Expect a dark-tilted treble that keeps excitement in check. Sibilants are dull, but so is everything else.
Dynamics C+
Dynamics feel competent, bringing energy without the finest detail. It carries energy without sounding aggressive.
Soundstage B
Good soundstage with proper width and depth, placing instruments in clearly defined positions. Instruments sit in their own lanes.
Gaming D-
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.

Average Technical & Tuning Grades

Average Tunign Grade

C
  • Expect a patchy tonal profile that makes instrumentation feel mismatched. EQ is almost mandatory to tame the response.

Average Technical Grade

C-
  • Details smear quickly, leaving the presentation cramped and low on definition. You'll notice smearing on even moderately layered songs.
Bass C
It keeps the low end tidy, though energy and weight remain limited. It favors balance over excitement.
Mids B-
Expect a competent midrange that keeps vocals grounded and instruments clear. Tone is acceptable across multiple genres.
Treble C-
Treble performance is average, audible but short on refinement. There's acceptable presence but limited finesse.
Dynamics D-
Expect constrained dynamics that blur the edges of quieter details. It struggles to render sudden changes.
Soundstage C+
You start to perceive distinct rows of players even if the ceiling still feels low. Layering is present but still modest.
Details C-
You get the outline of textures, though the finer brushstrokes remain faint. Background information is audible but soft.
Imaging C-
You can tell where things generally sit, though exact locations feel blurred. Center vocals sit mostly where expected.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.
