Very well tuned warm/bassy set. Not basshead like the Rosefinch, but still has good bass impact as well as upholding enough treble extension.

Average Technical & Tuning Grades

Average Tunign Grade

C
  • Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.

Average Technical Grade

C+
  • Satisfactory technical performance. Handles basic detail retrieval adequately in most tracks. Maintains reasonable cohesion in simpler arrangements.
Bass B-
Average bass performance - present but unremarkable. Has reasonable texture but lacks depth and physicality.
Mids A-
Excellent midrange with natural timbre and great detail retrieval. Vocals are forward and emotive with lifelike instrument reproduction.
Treble C+
Decent treble with acceptable extension and detail. Can sound slightly unrefined but avoids being harsh or sibilant.
Dynamics C-
Average dynamics - passable but unexciting. Transients are rounded and micro-dynamics lack refinement.
Details C+
Decent detail retrieval. Handles most textures adequately though micro-details and ambient cues could be more pronounced.
Imaging C+
Decent positional accuracy. Good left/right placement with acceptable center image, though depth positioning is approximate.
Gaming C+
Fundamental left/right positioning with limited depth perception. Works for non-competitive gaming but lacks precision.
