Final A4000 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

D+
  • The tuning lacks refinement, jumping between dull and shouty without settling. Vocals frequently sound off-kilter.

Average Technical Grade

E+
  • A foggy, one-dimensional presentation wipes out layering and obscures the finer points of a mix. Spatial cues barely register at all.
Mids C-
It delivers a workable midrange that could benefit from smoother transitions. Timbre isn't quite convincing yet.
Treble E+
Expect a dark-tilted treble that keeps excitement in check. Sibilants are dull, but so is everything else.
Dynamics D
Dynamics come across throttled, leaving energetic moments underwhelming. Energetic passages land with a thud.
Soundstage C+
It pushes sound outward confidently while leaving height development as an unfinished idea. Height remains subtle but detectable.

Premium CNC aluminum build, versatile tuning nozzles, and exceptional accessories including modular cable. Warm, lush sound with punchy bass and natural mids ideal for vocals.

Treble lacks air/sparkle for some, mid-bass warmth occasionally blurs definition. Soundstage width is average despite good depth.
