Average Technical & Tuning Grades

Average Tunign Grade

B-
  • Expect a friendly tonal balance that could use polish but remains inviting. Great for casual listening, less so for purists.

Average Technical Grade

B
  • Technical ability is serviceable, keeping basic detail intact across simpler tracks. It keeps up with acoustic tracks without much fuss.

Bass stays subdued, content to hover in the background. It keeps things tidy, yet unremarkable.
Mids B-
The region sounds agreeable overall, delivering clarity without flashiness. Slight warmth keeps things easy-going.
Treble C
The top end sounds acceptable but lacks the smoothness of higher tiers. Air is hinted at more than delivered.
Soundstage A-
Immersion steps up dramatically as width, depth, and height integrate into a cohesive hologram. Everything sounds naturally spaced.
Details C+
Decent detail retrieval that handles most textures while leaving some micro-information understated. Most textures come through cleanly.
Imaging B+
Good imaging with precise instrument placement and clear front/back localization. Positions snap into place convincingly.
