Synergy · 3 masters · 21 checks · 5 tiers
Three masters.
One rubric. Five tiers.
Every system runs three independent synergy readouts. Signal grades the electrical chain end-to-end. Room grades how the room loads what the speakers are doing. Character describes how the system will sound. Each runs the same physics-grounded checks, gets the same five-tier scale, and never averages into the others.

The active check set differs by transducer class. Switch tabs to see what each chain is graded on.
— the masters · speakers
Three masters, scored independently.
A worst-outcome rule applies inside each master — one fail in Signal caps Signal at Detuned; it doesn't touch Room. Tap a card to read the master's full check set.
Does the room load the speakers the way they were designed for — placement, modes, geometry, SPL in this volume?

How will the system sound — warmth, soundstage, top-end character? Descriptive, not pass/fail.

— the masters · headphones
One master scores, one describes.
For headphones, Signal swaps two checks in (headphone power + damping) and drops three (power, SPL headroom, crossover routing don't apply). Character stays a descriptive layer in development.
Can this electrical chain drive these headphones at this impedance, with enough damping and headroom?

How will the headphones sound — driver type, pad material, cup design? Descriptive, not pass/fail.
