"if you are measuring the right things” agreed 100%, tests should be aligned with real sound performance metrics.
"I can swap out a cap of same value in a speaker crossover”
-capacitor has many electrical characteristics beyond capacitance and max voltage values, to name a few - ESR (equivalent series resistance), inductance, resonance frequency etc. In general, two identical capacitors, matched by all characteristics, will perform the same in speaker with crossover. Some type of capacitors, oil capacitors (I am using those in my speakers) for example, have less resonances, thus produce less distortions, or “coloration” in other words.
"Also explain how two different amps that measure exactly the same can sound quite different”
-power amplifiers mostly measured using ideal, Re-Z, loads (e.g. 4/6/8 Ohms). Real speakers with cables, crossovers, drivers, and finally resonating cabinets, never match any of ideal loads, and have complex frequency/power-level dependent impedance.
