Average Technical & Tuning Grades
Average Tunign Grade
C+- 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 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.

Has the technical chops but is sharp and fatiguing. Crin Youtube Channel

64 Audio U4s reviewed by: Jaytiss
It's a solid set, with great build quality, but sonically isn't the specialist that I want it to be. Jaytiss Youtube Channel
64 Audio U4s reviewed by: Precogvision
Fantastic colored tonality with options, and the unique technical qualities to back it up. M12/M15 modules recommended. Precogvision Youtube Channel

64 Audio U4s reviewed by: Smirk Audio
A tastefully colored U12t with a more intimate soundstage, a cutback in technicalities, and more bass realism.
