Tanchjim Origin Scorings

Average Technical & Tuning Grades

Average Tunign Grade

B+
  • The tuning leans easygoing, yet occasional unevenness nudges it away from greatness. A bit of EQ polish can smooth things nicely.

Average Technical Grade

A-
  • You get a controlled, composed performance, marrying decent clarity with a still-modest sense of space. A safe technical performer for the price bracket.
Mids A-
It delivers an excellent midrange that feels vibrant and true to life. It balances clarity with natural smoothness.
Treble A-
Highs feel superbly executed, revealing micro-detail without hint of sibilance. Highs stay smooth even at volume.
Dynamics C+
You get reliable macrodynamics, with micro shifts that remain only adequate. A reliable performer for most tracks.
Soundstage A+
It crafts a floating sphere of sound where directional cues shimmer with precision. Layering remains stable even when pushed.

Open Audio Siren Scorings

Average Technical & Tuning Grades

Average Tunign Grade

C+
  • Expect a friendly tonal balance that could use polish but remains inviting. Great for casual listening, less so for purists.

Average Technical Grade

C-
  • Even moderate complexity exposes the limited resolution and narrow sense of space. Technical fans will find it lacking.
Mids C+
Expect a competent midrange that keeps vocals grounded and instruments clear. Tone is acceptable across multiple genres.
Treble C-
The top end sounds acceptable but lacks the smoothness of higher tiers. Air is hinted at more than delivered.
Dynamics C+
It offers fair punch and contrast, though micro-dynamics could be sharper. Impact is satisfying for day-to-day use.
Soundstage C+
It pushes sound outward confidently while leaving height development as an unfinished idea. Height remains subtle but detectable.
