A-Fearless S4 Scorings
Average Technical & Tuning Grades
Average Tunign Grade
B-- Flawed execution of tonal character. Noticeable peaks/dips affect timbre and coherence. May suit specific genres but lacks refinement.
Average Technical Grade
B-- Competent but unremarkable. Decent detail retrieval in quieter tracks, though busy sections challenge cohesion. Imaging is average, lacking depth.

Average Tunign Grade
A-- Competent tonal approach with minor technical flaws. Noticeable but not distracting quirks. Decent genre versatility.
Average Technical Grade
A-- Above average technicalities. Handles separation and detail adequately in simpler tracks, but complex passages remain challenging. Soundstage is modestly sized with acceptable imaging.

Tonally accurate though can be a little heavy with its upper midrange. Crin Youtube Channel

Binary Dynaquattro reviewed by: Jays Audio
Natural vocals, good treble extension, bass is tight and more resolving vs 61t and Davinci. Overall very well balanced and clean. There are some small peaks at 8-10k and 15-20K which can be an issue on some songs, and there is masking around 4-8k region, but overall, solid all-rounder. Jays Audio Youtube Channel

Excellent bass, vocal-forward tuning, and natural timbre. Hard to drive, could use more treble extension. Shines when driven properly.Gizaudio Axel original ranking
