Average Technical & Tuning Grades
Average Tunign Grade
B-- Generally enjoyable tonal character with some noticeable unevenness. Maintains listenability while showing room for refinement in frequency balance.
Average Technical Grade
C- Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.

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.
