Measurement over impressions

A frequency-response plot and a target delta are reproducible; "warm and musical" isn’t.

Audio Notes
Measurement-first notes on audio gear — what actually changes the sound, and the EQ curves to back it up.

Audiophile claims are mostly untestable — these aren’t
Most audio writing is adjectives. I wanted a small, honest set of notes grounded in measurements: what a headphone actually does, how far it sits from a sensible target, and the specific EQ that closes the gap.
These write-ups aren’t a product — they’re the reasoning (and the curves) that became the preset EQ profiles shipped in Aria.
From measurement to a preset
Each note follows the same path: measure, compare to a target curve, derive a minimal parametric EQ, then verify by ear and re-measure.

What I chose, and why
Decision
Minimal EQ
over aggressive correction
A few well-placed bands beat a wall of filters — less phase weirdness, and it maps cleanly onto Aria’s 10-band EQ.
