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.
