Great observation, Roscoeiii.
Any ZYX with the gold coil wire will sound soft, laid back, mellowed, smoothed, etc. Silver is the same, but less so. Copper coils provide closest to lifelike rise times, dynamics, speed and "jump".
I've A/B/C'd several ZYX models with the different coils and heard the the same results. The difference between them is not subtle.
